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.

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.

Push-to-Connect Tube Fittings for Drinking Water
- Temperature Range: 35° to 150° F
- Tubing: See table
- Specifications Met: NSF/ANSI 61
Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity 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. All meet NSF/ANSI 61 for use in drinking water systems.

Push-to-Connect Fittings for Plastic Tubing—Food and Beverage
- Temperature Range: 35° to 140° F
- Tubing: See table
- Specifications Met:
White Polypropylene: NSF/ANSI 51, NSF/ANSI 61
Black Polypropylene: FDA Compliant 21 CFR 176.170, NSF/ANSI 58, NSF/ANSI 372
Acetal: NSF/ANSI 51, NSF/ANSI 61
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.
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.
