10mm to Double 14mm Joint Adapter
A specialty borosilicate adapter that takes one 10mm male joint on the bottom and splits to two 14mm female joints on top. Run two bangers, two bowls, or one of each off a single rig — handy for tandem dabs or shared sessions.
- Material: Thick borosilicate glass
- Bottom joint: 10mm male
- Top joints: Two 14mm female (one of each on a shared base)
- Use case: Tandem bangers, dual bowls, shared dab sessions
- Approx height: 2.5"
- Free U.S. shipping on orders over
This isn't a piece you'll find on every shelf. Most adapters convert one joint to one joint — this one branches a single 10mm male into two parallel 14mm female slots. We picked it up because dab fans kept asking for a way to run two bangers without buying a second rig, and a Y-adapter is the cleanest answer.
Key Features
- Dual 14mm tops: Two female joints positioned to clear most banger and bowl footprints.
- 10mm male base: Drops into any 10mm female joint on a rig or bong.
- Borosilicate construction: Same glass used for premium dab rigs — handles thermal cycling without micro-fractures.
- Compact form factor: About 2.5" tall, won't tip a small rig.
- Smooth ground joints: Glass-on-glass seal, no pull-through air leaks.
Who It's For
Dabbers running tandem bangers who want one banger heating while the other cools. Shared session crews who'd rather pass two bowls than wait on one. Glass collectors who like unusual configurations.
Worth Noting: Both 14mm joints share airflow with the 10mm base, so both bangers/bowls vacate together. This is by design — it lets you torch one banger while the other clears. If you want fully isolated chambers, you'll need a separate adapter and recycler. Browse our quartz bangers to pair with this piece.

The adapter is borosilicate glass, about 2.5 inches tall and 1.75 inches across the top. The base is a 10mm male joint, and the top splits into two parallel 14mm female joints. It works with any rig or bong that has a 10mm female stem, and accepts any standard 14mm male banger or bowl.
Care & Cleaning
Soak in 91% isopropyl alcohol with coarse salt for ten minutes, then rinse with hot water. Both ground joints can be polished with a Q-tip and ISO if residue builds up at the seal. Avoid extreme temperature swings — never run cold water through the adapter immediately after a hot dab.
FAQ
Will this fit my rig?
If your rig has a 10mm female joint, yes. The adapter's base is a 10mm male. Most modern dab rigs and small bongs use 14mm joints, so this adapter is for the smaller 10mm rigs that have become popular for low-temp dabs.
Can I use both bangers at the same time?
Both 14mm slots share airflow with the 10mm base, so yes — you can heat one banger while the other cools, then pull from whichever is at temp. They don't isolate, so vapor from both will draw through together if both are loaded.
What can I put in the 14mm slots?
Any standard 14mm male banger, flower bowl, dry herb piece, or carb cap with a built-in joint. A common setup is one banger and one bowl, or two matched bangers for tandem dabbing. See our 14mm banger lineup.
Is this fragile?
Borosilicate glass is durable but it's still glass. Drop it on a hard floor and it can chip the joint. We recommend pulling the adapter when you're not using it and storing it in a soft case or padded drawer.
