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.

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Also known as JIS (Japanese Industrial Standard) fittings.

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

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.
