What Are Bong Adapters & Attachments?

Bong adapters and attachments are glass components that modify, convert, or expand the functionality of your water pipe. An adapter changes the joint size or gender of your bong — for example, converting an 18mm female joint to accept a 14mm male bowl. An attachment adds entirely new capability, like turning a standard bong into an oil rig with an oil burner attachment, or repositioning the bowl with a drop-down sidecar. These are small, affordable pieces that eliminate the need to buy a whole new water pipe every time your setup needs change.

Types of Bong Adapters & Attachments

Glass Size Adapters

Size adapters bridge the gap between mismatched joints. The most common conversion is 18mm-to-14mm (and vice versa), letting you use a 14mm bowl or banger on an 18mm bong. Our 420º Below adapters come in female-to-female, male-to-female, and male-to-male configurations to cover every combination.

Gender Converters

If your bong has a male joint but your accessory requires a female connection (or the other way around), a gender converter solves the problem instantly. These short glass pieces slot between your bong and your bowl, banger, or attachment to flip the joint gender without altering the size.

Drop-Down Adapters & Sidecars

Drop-down adapters extend the bowl or banger downward and away from the main body of the bong. This serves two purposes: it moves the heat source further from the glass to prevent heat stress, and it catches reclaim that would otherwise drip into the water chamber. Our sidecar-style drop-downs also shift the joint to the side for a more comfortable angle during use.

Oil Burner Attachments

An oil burner attachment converts any standard bong into an oil rig. These feature the signature glass bulb on a male joint stem and slide directly into your water pipe’s female joint. Available in 10mm, 14mm, and 18mm, including coloured and novelty designs like the Skull oil burner attachment.

Quartz Bangers

Quartz bangers are bucket-shaped attachments built specifically for dabbing concentrates. Made from quartz crystal rather than borosilicate glass, they handle extreme torch heat without cracking. Our 420º Below 10mm 90° banger is precision-ground for an airtight fit and even heat distribution across the bucket floor.

Downstems & Replacement Parts

Downstems carry smoke from the bowl joint down into the water chamber. If yours breaks or you need a different length, our replacement downstems come in standard sizes with ground glass joints for a snug, rattle-free fit.

How to Choose the Right Adapter or Attachment

Picking the right piece requires knowing two things about your bong: joint size and joint gender.

Step 1 — Measure your joint size: Use the dime/penny test. Dime fits but penny doesn’t = 14mm. Penny fits = 18mm. Some smaller rigs use 10mm joints.

Step 2 — Identify your joint gender: If your bong has an open socket that you insert a bowl into, it’s a female joint. If it has a protruding glass stem, it’s a male joint.

Step 3 — Decide what you need: Converting sizes? Get a size adapter. Flipping gender? Get a gender converter. Adding oil capability? Get an oil burner attachment. Protecting your glass from heat? Get a drop-down.
