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.

Low-Temperature D.O.T. Push-to-Connect Tube Fittings for Air
- Temperature Range: -40° to 210° F
- Tubing: Use with hard (Durometer 65D) nylon plastic
- Specifications Met: D.O.T. FMVSS 571, SAE J1131, SAE J2494-1, SAE J2494-3
Suitable for use in air brake lines, these fittings meet Department of Transportation FMVSS 571 safety standards for low-temperature 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. 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. They have good corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads. The male threads have an acrylic sealant applied to protect against leaks.

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.
