Plastic On/Off Valves with Push-to-Connect Fittings for Drinking Water
Female × Push
to Connect
- Valve Type: See table
- For Use With: Drinking Water
- Seal Material: EPDM Rubber
- Specifications Met: NSF/ANSI 61
Insert your tubing into the fittings of these valves with just a push—the internal rings will grip it tight. Made of plastic, these valves are a lightweight alternative to metal valves. All meet NSF/ANSI 61 for safe use with drinking water. Since they have a small, short handle, they can fit into tight spots and sit side by side.
Polypropylene valves are more flexible than PVC valves, so they’re better at handling movement and vibration without cracking.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
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.

Plastic Threaded Precision Flow-Adjustment Valves
- Valve Type: Needle
- For Use With: Water, Air, Argon, Helium, Krypton, Neon, Xenon
- Seal Material: EPDM Rubber
Plastic provides a lightweight alternative to metal valves. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. These valves have a hex nut and threads below the handle for mounting through instrument panels.

Threaded Precision Flow-Adjustment Valves for Chemicals
To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a fluoroelastomer seal and a plastic body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
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.
