The two ends
- End A
- Beer shank (7/8-14, 3/16 bore) (7/8"-14 ends, 3/16" bore)
- End B
- US beer nut (hex tailpiece nut) (7/8"-14 (1" hex))
- A seals on
- beer nut and washer at the back, faucet coupling nut at the front
- B seals on
- compresses a rubber washer between the tailpiece and the shank end
- Part needed
- none, direct fit
A beer shank is 7/8-14 on the back end, so a beer nut threads straight on and draws a tailpiece against the shank face. This is the standard back-of-shank joint on every North American draft build.
The washer between the tailpiece and the shank face does the sealing, so a weeping back end means a missing or flattened washer. Do not overtighten the beer nut to stop a drip; replace the washer instead.
