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.

For Use With: Air, Lubricated Air, Water,
except Manifolds with Swivel: Air, Water
Temperature Range: 32° to 100° F
Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber

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.

Fittings with thread sealant offer extra protection against leaks.

Manifold Adapters (Intermittent Swivel), Male Threaded Pipe × Tube

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

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.

Male
Threads
with Gasket

Temperature Range: 0° to 175° F
Tubing: Use with firm (Durometer 85A-100A) nylon plastic or polyurethane rubber
Specifications Met: ISO 14743

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads. With a nylon body and nickel-plated brass threads, these fittings are lighter than most metal fittings, and withstand corrosion better than plain brass threads. They also have a reusable gasket to guard against leaks. Connect the tube ends to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect them, push the release ring and pull the tubing out of the fitting. These fittings are sometimes known as instant fittings. All meet ISO 14743, which is an international standard for push-to-connect fittings for plastic tubing.

Low-Temperature/High-Pressure D.O.T. Push-to-Connect Tube Fittings for Air

Temperature Range: -40° to 200° F
Tubing: Use with hard (Durometer 65D) nylon plastic
Specifications Met:
Cartridges: D.O.T. FMVSS 571, SAE J2494-4, SAE J1131
All other fittings: D.O.T. FMVSS 571

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards. Also known as instant fittings, they connect to tubing with a simple push, and an internal gripping ring and O-ring will hold the tubing tight. A built-in tube support slips inside the tubing to prevent it from collapsing. To disconnect, push on the release ring and pull the tubing out of the fitting. All have good corrosion resistance.

Weld-Spatter-Resistant Push-to-Connect Tube Fittings for Air and Water

Temperature Range: 32° to 100° F
Tubing: Use with firm or hard (Durometer 90A-50D) nylon plastic or polyurethane rubber

Made of flame-resistant material, these fittings are good for welding and other applications where sparks occur. 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.
