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.

Plastic Quick-Turn Tube Couplings for Air and Water

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.

Stainless Steel Quick-Turn Tube Couplings for Air

Made of stainless steel, these couplings stand up to wet environments.

Brass Quick-Turn Tube Couplings for Air

These brass couplings have good corrosion resistance.

Plastic Quick-Turn Tube Couplings
with Shut-Off for Air and Water

A built-in shut-off valve stops the flow when the coupling is separated, so there’s no need to worry about air or water spilling from your line. Couplings are plastic, which is lighter in weight than metal couplings.

Quick-Turn Couplings for Stainless Steel Tubing

Also known as luer lock couplings, these consist of a plug and socket that connect with a half turn. Use in low-pressure applications up to 30 psi.

Check Valves with Quick-Turn Fittings

Also known as luer lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line.
