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
Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
Specifications Met: ISO 14743, except 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.

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.

Brass Push-to-Connect Tube Fittings for Air

Temperature Range: 0° to 200° F, except nylon plastic fittings are 0° to 150° F
Tubing: Use with hard nylon plastic or polyethylene plastic

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.

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: D.O.T. FMVSS 571

In addition to handling low temperatures, these fittings can also withstand higher pressures than other push-to-connect D.O.T. fittings. Commonly used in air brake lines, they meet Department of Transportation FMVSS 571 safety standards. Fittings connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Fittings have a built-in tube support that slips inside the tubing to prevent it from collapsing. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings are also known as instant fittings. They 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.
