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 Stainless Steel Threaded Pipe Fittings
Use these fittings in a low-pressure pipe line.
304 stainless steel fittings have very good corrosion resistance.
Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration. Locknuts that meet DIN 431 comply with international standards for pipe fitting locknut dimensions.
NPTF (Dryseal) threads and NPSL (National Pipe Straight Locknut) threads are compatible with NPT threads.

Compact Extreme-Pressure Steel Threaded Pipe Fittings
These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance. BSPP and metric male threads have a gasket and washer to prevent leaks.
