About Pipe and Fittings

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

Push-to-Connect Tube Fittings for Air

Temperature Range: 0° to 170° F, except polybutylene plastic fittings are 32° to 140° F
Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
Specifications Met: ISO 14743, except cartridges and polybutylene plastic fittings

Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.

Identification rings (sold separately) snap over the release ring so you can color-code your lines.

Clips (sold separately) align and organize your tubing and fittings.

BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Brass Push-to-Connect Tube Fittings for Air

Temperature Range: 0° to 200° F, except Tube Stem Straight Connectors are 0° to 150° F, and Plugs are 0° to 170° F
Tubing: See table

These fittings offer good protection against corrosive environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.

NPTF (Dryseal) threads are compatible with NPT threads.
