A brass hexagon coupling is the female counterpart to the hex nipple. It connects two male threads, and its hex body gives a positive spanner grip that round sockets lack, which matters when holding one side still while tightening the other. On air lines it links a male hose fitting to a valve tail, extends a male port, or joins short pipe nipples into a drop leg.
We stock equal couplings from 1/8" to 1" and reducing couplings for joining different thread sizes, in BSP and NPT. Brass handles the moisture in compressed air and repeated assembly well. Reducing couplings are useful at compressor outlets, where a larger pipe thread steps down to a hose fitting. In drop legs, couplings join short nipples to ball valves and filter regulators.
