About Pipe and Fittings

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

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Chrome-plated brass fittings are shinier and withstand corrosion better than nickel-plated brass fittings.

Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.
