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.

Compatible with Japanese-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.

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.
