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

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

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

With few moving parts to wear out, these valves withstand frequent opening and closing, pulsating flow, and rapid flow reversal.

Also known as backwater valves, these valves prevent backflow of sewage and wastewater in drain, waste, and vent systems.

Weld to unthreaded metal pipe.

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

Bolt to ANSI flanges.

Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint.

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.

Also known as luer lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line.

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

Valves have a plastic body.

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

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

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.

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

Barbs grip onto tubing, providing a secure hold.

Valves have NPT connections for use with threaded pipe.

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.

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

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.

Attach these valves with NPT connections to threaded pipe.

Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose.

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

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.

Stop backward flow in outdoor faucets with garden hose thread (GHT) outlets.

Attach these arresters to the outlet connection of a regulator on a torch that cuts steel up to 11" thick.

Stop the reverse flow of gas in your regulator.
