Use these fittings for low-pressure applications in noncorrosive environments.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Metal hose fittings have better durability than plastic barbed hose fittings.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.
