Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

Fittings meet NSF/ANSI Standard 61 for drinking (potable) water.
