To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 150 psi.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. Also known as dry disconnects and double shut-off couplings, they have a shut-off valve in the plug and the socket for minimal fluid loss when disconnecting your hose line.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Tighten these threaded fittings with your hands for a secure connection in testing, flushing, venting, and plugging applications—no tools, tape, or sealant required.
