About Pipe and Fittings

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

Medium-Pressure Stainless Steel Threaded Pipe Fittings

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

316 stainless steel fittings have excellent corrosion resistance.

BSPP male threads have a gasket to protect against leaks.

Fluoroelastomer gaskets withstand high and low temperatures like silicone gaskets do, and also have some resistance to fuel and oil.

Miniature Medium-Pressure Stainless Steel Threaded Pipe Fittings

When space is at a premium choose these compact fittings. Though small in size, they have the strength to handle medium-pressure applications. Fittings are stainless steel for very good corrosion resistance.

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

Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. Made from fluoroelastomer, these gaskets resist chemicals, including benzene, butyl alcohol, and ethylene glycol. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
