A complete visual guide to every smoking accessory part — joints, percolators, ash catchers, dab components, and the accessories that tie your setup together.
A bong, rig, or pipe is made up of modular parts that each serve a specific function in moving, filtering, and cooling smoke. The bowl holds your material, the downstem channels smoke into water, percolators break smoke into bubbles for filtration, and accessories like ash catchers and adapters let you customize and upgrade your setup. Dab rigs add their own parts — bangers, carb caps, and terp pearls — designed specifically for vaporizing concentrates. Every part connects through standardized joint sizes and genders, so knowing the basics of joints and compatibility lets you mix, match, and upgrade with confidence.
What Are the Core Parts of a Bong?
Every bong, regardless of shape or size, shares the same five structural parts. Smoke starts in the bowl, travels through the downstem, collects in the water chamber, rises through the neck, and exits through the mouthpiece. Understanding what each part does helps you shop smarter and diagnose problems when something breaks.
- Bowl — the removable cup that holds your herb and lights it
- Downstem — the glass tube that channels smoke into the water chamber; diffused downstems have slits or holes that create smaller bubbles [2]
- Water chamber — the main body section filled with water where cooling and initial filtration occur
- Neck — the vertical tube connecting the water chamber to the mouthpiece; may include ice pinches for extra cooling [6]
- Mouthpiece — the top opening where you seal your lips to draw smoke through the bong
- Ice catchers (optional) — small glass pinches in the neck that hold ice cubes to reduce smoke temperature before inhalation
The bowl is the cup-shaped piece at the top of the bong where you load your material. It holds the herb in place while it burns and allows airflow into the downstem when you inhale. Bowls come in many shapes and sizes, and most are removable so you can switch them out for different styles or capacities. [1]
The downstem is the long glass tube that runs from the bowl down into the water chamber. It channels smoke from the bowl into the water below. Standard Downstems are simple tubes, but diffused downstems have small slits or holes at the bottom that break smoke into many tiny bubbles. Those extra bubbles increase the surface area of smoke that contacts the water, which changes how the hit feels. [1]
The water chamber is the wide middle section of the bong filled with water. This is where the bulk of cooling and filtration happens. Smoke bubbles through the water, which removes heat and some particulate matter before the vapor continues upward. The size and shape of the water chamber affects how much water is used and how stable the bong sits.
The neck is the vertical tube that connects the water chamber to the mouthpiece. Smoke travels up through the neck after leaving the water. Some necks have ice pinches — small glass pinches on the sides that hold ice cubes to further cool the smoke before it reaches your mouth. Ice catchers are a popular feature on many bongs because they provide an extra cooling step without adding complexity to the design. [1]
The mouthpiece is the top opening where you put your lips to inhale. It is shaped to form a seal against your mouth for comfortable, controlled draws. Some mouthpieces are wide and flattened, others are rounded. The size and shape of the mouthpiece affects how comfortable the bong is to use over time.

What Joint Size and Gender Do I Need?
The joint is the glass tube on your bong or rig where Accessories like bowls, downstems, and ash catchers attach. Getting the joint size and gender right is the single most important step when buying any accessory. The wrong size will not seal, and the wrong gender will not connect at all.
- Measure your joint — use the printed stamp or a ruler to confirm 10mm, 14mm, or 18mm before buying any accessory [3]
- Identify the gender — male joints insert into accessories; female joints receive them; check your pipe’s joint to know which you have [4]
- Match both size and gender — a 14mm male bowl only fits a 14mm female joint; same size but same gender means no seal [4]
- Check the product specification — every online listing includes joint size and gender in the specs; always confirm before purchasing
Bong joints come in three standard sizes. Ten millimeter (10mm) joints are found on small micro rigs and portable pipes. Fourteen millimeter (14mm) joints are the most common size on most bongs and rigs. Eighteen millimeter (18mm) joints are on larger pipes designed for heavy-use setups. [3] You must match the size exactly — a 14mm accessory will not fit an 18mm joint under any circumstances.
Glass joints also have a gender, and this is where many buyers run into trouble. Every joint is either male or female. A male joint is an outward-facing tube that inserts into accessories. A female joint is an opening that receives accessories. Here is the rule: opposite genders connect. A male bowl fits a female joint, and a female bowl fits a male joint. Same-gender connections do not seal and will leak every time. [4]
Before buying any accessory, check your pipe’s joint size and gender. Look at the glass tube near the base of the bowl — most bongs have the size printed or stamped there. You can also measure the inner diameter of the joint opening with a ruler. Write down the size (10mm, 14mm, or 18mm) and the gender (male or female) before you shop. If you are buying online, these details are listed in every product specification.
What Is an Ash Catcher and Do I Need One?
An ash catcher is a filtration accessory that attaches between your bowl and the bong joint. Its job is to trap ash and debris before they fall into the main water chamber. Think of it as a pre-filter that keeps your bong cleaner and extends the time between thorough cleanings. Ash Catchers are especially useful if you use your bong frequently, since they reduce how often you need to change the water and scrub the interior.
- Traps ash and debris before they reach the main water chamber, keeping your bong cleaner between deep cleanings [2]
- Works as a pre-filter — smoke passes through water inside the ash catcher before entering the bong, adding an extra stage of cooling and filtration
- Available in multiple styles — showerhead, tree, and honeycomb diffusers each produce a different draw feel and level of drag
- Reduces cleaning frequency — removing and cleaning a separate ash catcher is faster than cleaning the full bong interior
Ash catchers work the same way as the main water chamber — smoke passes through water inside the ash catcher, cooling it and catching particles before they move further into the bong. The difference is that the ash catcher is a separate piece that you remove and clean on its own schedule, rather than the main chamber you use every session.
Ash catchers come in several internal styles. Showerhead ash catchers use a center tube with holes that diffuse smoke downward into water, similar to a showerhead percolator. Tree ash catchers have multiple rigid arms that break smoke into bubbles. Honeycomb ash catchers have a flat disc with a grid of holes, offering high diffusion with relatively low drag. The style you choose affects how the hit feels and how much drag the ash catcher adds to your draw.
Not every setup needs an ash catcher, but they are one of the most cost-effective upgrades you can make. They cost less than a full cleaning session takes in time, and they significantly extend the life of your bong’s water clarity. If you want to keep your pipe cleaner with less effort, an ash catcher is a worthwhile addition. [1]
What Are the Different Types of Percolators?
A percolator is a filtration device inside a bong or rig that breaks smoke into many small bubbles as it passes through water. The goal is to increase the surface area of smoke that contacts the water, which means more cooling and more filtration before the vapor reaches your mouth. [7] Bongs can have one percolator or multiple stacked inside the same water chamber.
- Diffused downstem — a downstem with slits or holes at the bottom that break smoke into small bubbles as it exits; entry-level percolation, adds minimal drag [7]
- Inline perc — a flat horizontal disc with slits inside a tube; smoke passes through the disc and is diffused in one direction; balanced smoothness and drag [7]
- Tree perc — multiple rigid glass arms extending from a central base inside the water chamber; each arm has holes that create many small bubbles; high diffusion, more drag [7]
- Showerhead perc — a center tube with a wider head full of holes at the bottom; smoke exits downward through the holes like a showerhead; balanced diffusion with a smoother draw than tree percs [8]
- Honeycomb perc — a flat disc with a grid of small holes; smoke passes through the entire disc at once; high diffusion with relatively low drag compared to tree percs [8]
- Turbine perc — an angled disc with holes that creates a spinning vortex of water as you inhale; smoke is diffused through the spinning water; visually distinctive and cools efficiently [7]
- Matrix perc — a disc with a grid pattern that allows smoke to exit through multiple openings across the entire surface; 360-degree diffusion; smooth hits but higher drag [8]
- Fritted disc perc — a disc made from sintered glass particles (fused glass powder); extremely fine pores create very small bubbles and maximum diffusion; premium option for high smoothness [7]
Percolators add drag — the harder it is to pull air through the bong, the more resistance you feel on the inhale. High diffusion percs filter heavily but can feel restrictive. Low drag percs let you pull more freely but offer less filtration. Choosing a percolator is a trade-off between smoothness and ease of draw. [8]
Recycler bongs use a two-chamber design where water is pushed out of the first chamber and pulled back into the main body on each inhale. This creates continuous circulation that keeps water fresh and smoke moving. Recyclers are popular because they maintain clear water longer and provide a consistent, smooth draw throughout a session. [6]
Different percolator geometries produce very different experiences, even when the bong size and water volume are the same. A honeycomb perc and a tree perc on two identical bongs will feel noticeably different when you use them side by side. Knowing what each style offers helps you pick a bong that matches how you actually like to smoke.
What Parts Make Dab Rigs Different From Bongs?
Dab rigs are designed for vaporizing concentrates, not burning dried herb. Because concentrates vaporize at higher temperatures than combustion, dab rigs need different components than flower bongs. The three parts unique to dab rigs are bangers, Carb Caps, and Terp Pearls. Each serves a specific function in the vaporization process.
- Banger — the quartz bucket nail that holds concentrates; 90-degree bangers suit upward-facing joints, 45-degree bangers suit angled joints [5]
- Carb cap — covers the heated banger to trap heat and allow lower-temperature vaporization; also directs airflow across concentrates to maximize vaporization [5]
- Terp pearls — small spinning beads inside the banger that distribute heat evenly across concentrates during inhalation [5]
A banger is a bucket-style nail shaped like a deep cup that holds concentrates in a dab rig. Bangers are typically made from quartz because it can withstand repeated heating cycles without cracking. [5] Bangers come in two main angles. A 90-degree banger has the bucket facing straight up, which works best with joints that face upward or at the ceiling. A 45-degree banger has an angled neck and is designed for rigs with slanted or angled joints, allowing the banger to sit at a more comfortable angle for dabbing. [5]
A carb cap covers the banger after you heat it. When the banger is open to air, concentrates vaporize too quickly and some material is wasted. Covering the banger with a carb cap traps heat inside the cup, lowering the effective temperature and allowing you to get full vaporization at a controlled rate. [5] Carb caps also have a directional airflow feature — the cap funnels air over the concentrates in a way that helps you get every last bit of material off the banger walls.
Terp pearls are small spherical beads placed inside a banger after you heat it. When you inhale through the carb cap, air spins the terp pearls inside the banger. The spinning motion distributes heat more evenly across the concentrates, which gives you consistent vapor quality from the first dab to the last. [5] They are a low-cost accessory that meaningfully improves the dabbing experience, especially for larger bangers where heat distribution can be uneven.
Which Accessories Upgrade Any Smoking Setup?
Beyond the core parts every bong needs, several accessories can improve your setup’s performance, comfort, and longevity. Some fix common problems like joint stress or unwanted ash. Others add functionality like ice cooling or more even airflow. These parts are widely compatible across brands as long as you match the joint size and gender.
- Ice catchers — glass pinches in the neck of a bong that hold ice cubes; adding ice cools smoke further before it reaches the mouthpiece for a less harsh inhale [1]
- Keck clips — small fastening clips that secure glass-on-glass joints and prevent accidental separation when removing bowls or downstems [9]
- Drop-down adapters — extensions that lower the accessory attachment point below the main joint, reducing heat stress on the joint and moving accessories farther from the main body [2]
- Multi-hole bowl slides — bowl slides with several small openings instead of one large opening; distribute airflow more evenly for a controlled burn and draw
Keck clips are small clips that secure glass-on-glass joints to prevent accidental separation. When you remove a bowl or downstem from a removable setup, the joint can slip and cause damage to your glass. Keck clips hold the two pieces together so they cannot separate unexpectedly. [9] They are inexpensive, easy to install, and especially useful for setups where you change bowls frequently.
Drop-down adapters lower the attachment point below the main joint, which moves heat-generating accessories farther from the main body of the bong. They are especially useful for dab rigs, where the banger can radiate heat back toward the joint and fingers during use. Drop-downs also reduce stress on the main joint from heavy accessories, which extends the life of the rig. [2]
Multi-hole bowl slides distribute airflow through several openings rather than one large hole. This creates a more even burn of your material and can affect how the hit feels. Some smokers prefer multi-hole slides because they produce smaller, more controlled draws compared to a single large opening. These slides are available in the same joint sizes as standard bowls, so compatibility follows the same rules.
What Are Common Questions About Smoking Accessories?
How do I know if my bong is 14mm or 18mm?
Look at the joint — the glass tube near the base of the bowl. Most bongs have the size printed on the joint or in the product description. You can also measure the inner diameter of the joint opening with a ruler. Standard sizes are 10mm (micro/nano), 14mm (most common), and 18mm (larger pipes).
What happens if I mix male and female joints of the same size?
Nothing — that is exactly what you want. Male and female joints must be opposite genders to connect properly. A 14mm male bowl fits a 14mm female joint. Same-gender connections (male-to-male or female-to-female) will not seal and will leak.
Do I need an ash catcher with every bong?
No, ash catchers are optional. They attach between your bowl and the bong joint to trap ash and debris before they reach the main water chamber. This keeps your bong cleaner longer and reduces how often you need to change the water. They are especially useful for heavy-use setups.
What is the difference between a 90-degree and 45-degree banger?
A 90-degree banger has the bucket facing straight up (at a 90-degree angle to the joint) and works best with joints that face upward or at the ceiling. A 45-degree banger has an angled neck and is designed for rigs with slanted or angled joints, allowing the banger to sit at a more comfortable angle for dabbing.
Do percolators make hits smoother or just cooler?
Percolators break smoke into many small bubbles, which increases the surface area of smoke that contacts water. More contact means better cooling. Whether a hit feels smoother depends on the percolator type — honeycomb percs generally offer high smoothness with low drag, while tree percs offer aggressive diffusion with more drag.
Can I use bong accessories on a dab rig?
Yes, as long as the joint size and gender match. Ash catchers, Keck clips, and drop-down adapters all work with both bongs and dab rigs if the joint specifications align. Just make sure you check the joint size (10mm, 14mm, or 18mm) and gender before purchasing any accessory.
How Do You Choose the Right Parts for Your Setup?
Every part of a bong, rig, or pipe exists to serve a specific purpose. The bowl holds your material. The downstem and percolators manage how smoke is cooled and filtered. The joint system lets you mix and match accessories across brands and setups. Understanding what each part does gives you the knowledge to upgrade intelligently and troubleshoot when something does not work.
Start with your joint size and gender — that single piece of information determines what accessories are compatible with your pipe. From there, decide what you want from your setup. If you want cleaner hits with less maintenance, add an ash catcher. If you want maximum filtration, look for a bong with a honeycomb or tree percolator. If you are getting into dabbing, start with a quality banger and a carb cap, then add terp pearls once you have the basics down.
Parts and upgrades are where your setup becomes personal. The standardized joint system means you are not locked into one brand or one configuration. You can build, swap, and improve over time. Treehouse Lifestyle carries a full selection of bowls, downstems, ash catchers, carb caps, terp pearls, and other accessories to help you build exactly the setup you want — and with free shipping on orders over $150, upgrading is affordable.
