10, 14 and 18 mm bangers: which joint goes on which rig
| Joint | Also listed as | Wide end of the male joint | Bangers in stock | Rigs in stock |
|---|---|---|---|---|
| 10 mm | 10.0 mm | 8 | 0 | |
| 14 mm | 14.5 mm | 14.5 mm | 22 | 48 |
| 18 mm | 18.8 mm, 19 mm | 18.8 mm | 2 | 0 |
The widths are the standard taper sizes for ground glass joints: 10.0, 14.5 and 18.8 mm at the wide end of the male joint, from the ASTM E676 table that Scientific Machine publishes. Shops print the same joints as 14 or 14.5 mm, and as 18, 18.8 or 19 mm.
The rule for a banger and a rig
The banger's joint and the rig's joint are the same size and opposite genders. A rig with a 14 mm female joint takes a 14 mm male banger; a rig with an 18 mm male joint takes an 18 mm female banger. The angle has to match as well, which the 45 or 90 guide covers.

Every rig here whose listing gives its joint is 14 mm, and nearly all of them are female. 14 mm male bangers are the biggest group here too.
When the sizes don't match
An adapter sits between the rig and the banger and changes the joint size. These are in stock:

Glass Joint Size Adapter
From $5.49
Fits your rig
The Glass Joint Size Adapter (From $5.49) comes as 14 mm to 18 mm or 10 mm to 14 mm. The 10 mm Joint Transition to Double 14 mm Joint ($14.99) goes into a 10 mm female joint and gives two 14 mm female joints on top, by its listing.
Joint pages
Each rig joint with three or more pieces in stock has its own page in the Fit Index, listing the bangers and reclaim catchers that fit it and the rigs that have it. The table above links each one.
The male or female guide explains how to tell which gender your rig's joint is.
Questions people ask
What's the difference between a 10 mm and a 14 mm banger?
The width of the joint. A 10 mm male banger goes into a 10 mm female joint, and a 14 mm male banger goes into a 14 mm female joint. One won't go on the other's rig without an adapter.
What sizes do bangers come in?
The joints come in 10, 14 and 18 mm, each male or female, at 45° or 90°. The bucket has its own width, which is what decides the carb cap. Every banger here lists its joints, and its bucket width wherever the maker gives it.
Is a 14.5 mm joint the same as a 14 mm joint?
Shops use both names for the same joint. 14.5 mm is the width at the wide end of a standard taper 14 mm male joint, and 18.8 mm is the same figure for an 18 mm joint.
