Color-Coded Quarter-Turn Shut-Off Valves for Hot and Cold Water
Quickly identify hot and cold water lines with these red or blue valves. The low-profile elbow shape and small handle are made to fit into tight spaces, such as plumbing outlet boxes (sold separately). Connect the NH/NST threads to a water hose on a washing machine or commercial plumbing fixture.
Valves with a solder-connect inlet are used for copper water lines.
Valves with a barbed inlet are compatible with Viega PEX tubing; attach them to your line with a crimping tool and crimping ring (both sold separately).

Plumbing Fixture Water Supply Tubes
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.

Plastic Push-to-Connect Tube Fittings for Chemicals
- For Use With: Inch: Alcohol, Hydrochloric Acid, Nitric Acid, Sodium Carbonate, Sulfuric Acid
Metric: Acetic Acid, Alcohol, Arsenic Acid, Benzoic Acid, Fluoboric Acid, Sodium Carbonate, Sulfuric Acid - Temperature Range: Inch: 0° to 270° F
Metric: 32° to 175° F - Tubing: Use with hard (Durometer 55D-60D) FEP plastic
Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Use these fittings in low-pressure applications.
PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.
Fittings with UNS threads are also known as faucet connectors; they attach directly to a faucet threaded inlet or water line.
