On/Off Valves with Barbed Fittings for Drinking Water





- Valve Type: Ball
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
Connect these valves to tubing with a ring and a crimping tool (both sold separately). Compatible with Viega PEX tubing, they have multiple barbs that grip onto tubing for a secure hold. They meet the strict standards of NSF/ANSI 61, so they’re safe to use with drinking water. Made of metal, these valves are more durable than plastic valves and withstand higher temperatures.
Valves with a solder-connect end give you a permanent, leak-tight connection to copper tubing. Also known as sweat fittings. Copper tube size is the accepted designation of the copper tubing industry, not the actual OD.
