Universal-Thread Push-to-Connect Tube Fittings for Air and Water


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.

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.
Fittings with PTFE thread sealant offer extra protection against leaks.
Metric male threads have either a gasket or a thread sealant to protect against leaks. BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

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

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

- 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.
Metric male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) male threads have a gasket or a washer and gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

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


Threads
with Gasket
- Temperature Range: 32° to 100° F
- Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber
The threads on these fittings mate with NPT, NPTF (Dryseal), BSPT, and BSPP threads. The male threads have a gasket to protect against leaks. Fittings are moisture and corrosion resistant, so they’re good for water and humid 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.

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.

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 Hot Drinking Water

- Temperature Range: 35° to 200° F
- Tubing: Use with hard polyethylene plastic
- Specifications Met: NSF/ANSI 51, NSF/ANSI 61
Run hot water through these fittings at temperatures up to 200° F. 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. Fittings are nylon for excellent impact and abrasion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
