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.

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.

Fittings that meet ANSI/MSS SP-114 adhere to high-quality standards for heat treating, material thickness, and marking.

304 stainless steel fittings have very good corrosion resistance.

316 stainless steel fittings have excellent corrosion resistance.

Alloy 20 stainless steel fittings have the best corrosion resistance of all the stainless steel fittings we offer. Alloy 20 stainless steel is also known as Carpenter 20 and resists cracking from stress and corrosion.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Threaded female x butt weld straight adapters are also known as half couplings.

Fittings with intermittent swivel rotate 360° as needed to allow movement in a rigid metal piping system.

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.

EPDM gaskets resist water, steam, ethanol, and ethylene glycol.

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 x 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.

Low-Pressure Stainless Steel Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection. Also known as Pressure Class 150 fittings, they are built for use in low-pressure applications. They adhere to high-quality standards for heat treating, material thickness, and marking.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
