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.

Low-Pressure Brass and Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Bronze Unthreaded Pipe Fittings

Snap a brazing ring (sold separately) into these fittings and braze them to unthreaded pipe for a strong, leak-resistant connection. Fittings are also known as Silbraze fittings. They are bronze, which is compatible with brass and has good corrosion resistance.
