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.

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 Fittings for Food and Beverage
- Temperature Range: 35° to 140° F
- Tubing: See table
- Specifications Met: See table
Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.
Polypropylene fittings have excellent impact and abrasion resistance. They meet NSF/ANSI standards for safe use with food. Some are also FDA compliant for indirect contact with food.
Acetal fittings resist moisture, so they won’t soften and lose strength in humid environments. They meet NSF/ANSI 51 for safe use with food and NSF/ANSI 61 for safe use with drinking water.
Black fittings have excellent UV resistance and are suitable for outdoor environments.

Wye-Shaped On/Off Valves with Garden Hose Threads
Convert one faucet into two, four, or five outlets.
All valves have shut-off outlets, so you can start and stop the flow to outlets individually. You can also use the shut-off to release pressure or drain residual water after disconnecting hose. Some valves also have open-flow outlets in addition to shut-off outlets. Open-flow outlets don't give you any flow control—they work like standard outlets.
Plastic valves are lighter in weight than metal valves, but they’re not as durable. Zinc valves are stronger and more resistant to wear and tear than plastic valves. Brass valves are stronger than plastic, zinc, and aluminum valves. Aluminum valves resist the highest pressures.
Toggle-switch handles easily flick on and off like a light switch.
Valves with TPR coating protect your hands by keeping the valve’s surface from getting too hot or cold.
Valves with a support brace can be secured against a wall for extra stability.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
