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.
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.
Black fittings have excellent UV resistance and are suitable for outdoor environments.
Fittings with UNS threads are also known as faucet connectors; they attach directly to a faucet threaded inlet or water line.
NPTF (Dryseal) threads are compatible with NPT threads.
