About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Grooved-End Iron Pipe Fittings

The grooved ends on these fittings connect to pipe with a clamp to easily install piping systems. Since there’s no heat or threading required, they provide quick access to a pipe line for routine maintenance. Fittings are also known as Victaulic fittings. They are for use in noncorrosive applications.

Clamps have a two-piece housing that can remain intact for installation.

Inline tees are also known as branch tees.

Standard-Wall Grooved-End Steel Pipe Nipples and Pipe

The grooved ends on this pipe connect to fittings with a clamp (sold separately) for an easy way to install piping systems. It is also known as Schedule 40. Pipe is welded, so it has a weld bead on the inside. Use it in noncorrosive environments.
