How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Jam Nuts for Turnbuckles
Tighten these nuts against the turnbuckle body to prevent the end fitting from unscrewing.

Extreme-Pressure Steel Threaded Pipe Fittings
The strongest steel fittings we offer, these can withstand extreme-pressure applications.
Galvanized and zinc-plated steel fittings have better corrosion resistance than plain steel fittings. PTFE-coated steel fittings have better corrosion resistance than galvanized and zinc-plated steel fittings.
Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.
