About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Brass Low-Pressure Barbed Tube Fittings for Air and Water

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings. Use them for low-pressure HVAC systems, drain lines, and other fluid transfer applications, as well as air lines where water vapor and condensate form. The barbs tightly grip tubing for a secure hold. For the best grip, make sure your tubing is squarely cut.

NPT adapters require thread sealant (not included) for a leak-tight seal.

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

Threads with Gasket

Temperature Range: 32° to 180° F
Tubing: Use with firm (Durometer 85A) polyurethane rubber

Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.

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. The barb grips onto tubing, providing a secure hold with no clamp required. 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.

Nickel-plated brass plugs and sockets have 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.
