About Pipe and Fittings

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

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 zinc-plated steel, which have better corrosion resistance than plain steel fittings.

Female × male 90° elbow adapters are also known as street elbows.

Inline tees are also known as branch tees. Right-angle tees are also known as run tees.

NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have either a gasket or a gasket and washer to prevent leaks.
