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.

Rated for at least four times the pressure of standard check valves for oil and fuel, these are often used in hydraulic applications with pressures up to 3,000 psi.

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

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

These valves open to allow flow in one direction and close when flow stops or reverses.

To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings.

Barbs grip onto tubing, providing a secure hold.

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Connections are NPT.
