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.

For use with threaded pipe, these valves are available with NPT, NPTF, BSPP, BSPT, and UNI/UNF (JIC) connections.

At 1 1/2" long or less, these valves fit in confined spaces.

The heat-resistant rubber seal withstands temperatures up to 500° F.

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

Visually inspect flow and debris accumulation through the transparent valve body.

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 fittings—no heat, solder, or flux required.

Visually inspect flow and debris accumulation through the transparent valve body.

For more durability than plastic, these valves have a metal body.

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

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