Plastic provides a lightweight alternative to metal.

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 3,000 psi.

Barbs grip onto tubing, providing a secure hold.

Two sleeves give the fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Insert tubing into the fitting—no heat, solder, or flux required.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves insert into a union fitting.

Insert tubing into the fittings—no heat, solder, or flux required.

Body is plastic.

Insert unthreaded pipe into the socket ends and bond with primer and cement to create a permanent, leak-tight connection.

Solder to copper tubing for a permanent, leak-tight connection.

These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F.

For more than twice the temperature rating of standard check valves for oil and fuel, these have a heat-resistant fluoroelastomer seal that can withstand temperatures up to 500° F.

To maintain sanitary standards in food, beverage, and dairy applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning.
