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.
Metric male threads have a gasket to protect against leaks.

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.

D.O.T. Brass Compression 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
Fittings meet Department of Transportation FMVSS 571 safety standards for air brake lines. They have a single sleeve (ferrule) that compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
