Check Valves with Push-to-Connect Fittings
Insert tubing into the push-to-connect fittings—no heat, solder, or flux required. These valves open to allow flow in one direction and close when flow stops or reverses.
Acetal valves are more wear resistant than PVC valves.

Heavy Duty Check Valves with
Push-to-Connect Fittings for Drinking Water
A metal body provides more durability than plastic. Insert tubing into the push-to-connect fittings—no heat, solder, or flux required. These valves meet NSF/ANSI 61 for use in drinking water systems. They open to allow flow in one direction and close when flow stops or reverses.
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.

Air Flow Check Valves
Inlet × Push-to-Connect
Female Outlet
Valves open to allow flow in one direction and close when flow stops or reverses.
Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
