How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Brass Low-Pressure Barbed Tube Fittings for Air and Water

A brass body provides protection against corrosive environments. Fittings have barbs that grip onto tubing.

Fittings with a single barb provide a smooth clamping surface for extra-tight connections that minimize leaks.

UN/UNF (SAE Straight) male threads with gasket provide extra protection against leaks. Also known as O-ring boss threads.

Brass High-Pressure Barbed Tube Fittings for Air and Water

Temperature Range: -40° to 250° F
Tubing: Use with hard (Durometer 65A-60D) EVA plastic, polyurethane rubber or PTFE plastic

These fittings can handle higher pressures than other brass barbed tube fittings for air and water. They have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Fittings are brass for good corrosion resistance.

Low-Profile High-Pressure Quick-Disconnect Tube Couplings for Air

Temperature Range: -30° to 250° F
Tubing: Use with firm or soft (Durometer 35A-90A) Buna-N rubber, EVA plastic, gum rubber, latex rubber, neoprene rubber, polyurethane rubber, PVC plastic or silicone rubber, except for fittings with pipe end

With no latch, these couplings have a compact design to fit in small spaces. They connect with a push and disconnect with a pull, so you can easily access your line. Couplings consist of a plug and a socket (sold separately). They have a universal connection, so the plugs will connect to any of the sockets regardless of the pipe or tube size. They are nickel-plated brass for very good corrosion resistance.

Note: For a complete coupling, order a plug and a socket.

Plugs, Barbed Tube

Barbed plugs and sockets insert into tubing and secure with a clamp.

Sockets, Barbed Tube

Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air won’t leak from your line.

Barbed plugs and sockets insert into tubing and secure with a clamp.
