About Pipe and Fittings

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

Extreme-Pressure Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications. PTFE-coated steel fittings have better corrosion resistance than galvanized and zinc-plated steel fittings.

Plugs with a 7/8" taper sit flush to the surface for a low profile.

PTF-SAE (Dryseal) threads are compatible with NPT threads.
