Overview
A nipple is a short length of male-threaded fitting used to connect two female fittings, or a fitting to a valve. Hex nipples have a hex in the centre for tightening; barrel nipples are plain; reducing nipples change size.
Empire Alloys turns brass nipples from in-house extruded hex and round bar, threading both ends concentrically on CNC machines.
