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

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

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

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.

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

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.

Valves have a plastic body.

The most chemical-resistant check valves in our offering, these have a PFA body to withstand methyl ethyl ketone, sodium hypochlorite, and other extremely harsh chemicals.

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

Plastic provides a lightweight alternative to metal.

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