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

Use these unthreaded flanges in low-pressure applications. Also known as Class 125 flanges.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Their small size makes these miniature fittings a good choice for cramped, confined spaces.

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

These junction blocks have threaded holes that allow air or fluid to flow at a 90° angle through the block. Use them to organize and separate multiple lines in your system.

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Connect these fittings to air tools for pneumatic applications.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.
