To achieve the maximum possible flow, internal components are designed to reduce flow resistance.

Plastic provides a lightweight alternative to metal.

Rated for up to twice the pressure of standard check valves, these can withstand pressures up to 2,000 psi.

For more durability than plastic barbed check valves, these have a stainless steel 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.

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

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.

Valves have NPT connections for use with threaded pipe.

Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.

To automatically shut off the flow of diesel fuel, fuel oil, kerosene, and oil in case of fire, these UL listed valves automatically close and the handle permanently fuses in place when the ambient temperature reaches 165° F.
