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

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.

Weld these valves to unthreaded pipe for a smooth, flush connection that provides maximum flow.

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.

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

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

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

The metal body is more durable than plastic.

These compact valves fit into standard sanitary quick-clamp fittings. All are FDA Compliant 21 CFR 177.2600 and have polished surfaces for easy cleaning.

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.

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