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.

BSPP, Metric, and
UN/UNF (SAE Straight)
Male Threads with Gasket

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.

Metric male threads have either a gasket or a thread sealant to protect against leaks.

Inline Tee Adapters (Intermittent Swivel), Tube × Male Threaded Pipe

BSPP, Metric, and
UN/UNF (SAE Straight)
Male Threads with Gasket

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

Inline tees are also known as branch tees.

Moisture-Resistant Push-to-Connect Tube Fittings for Air and Water

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. 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. They have good corrosion resistance.

Nickel-plated brass fittings have better corrosion resistance than unfinished brass fittings.

Metric male threads have a gasket to protect against leaks.

High-Temperature Brass Push-to-Connect Tube Fittings for Air and Water

Temperature Range: 0° to 300° F
Tubing: Use with firm or hard (Durometer 95A-65D) nylon plastic or polyurethane rubber
Specifications Met: ISO 14743

These fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water. 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. They are nickel-plated for very good corrosion resistance.
