About Pipe and Fittings

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

Metal Pipe and Pipe Fittings

Precision Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Standard-Wall Steel Threaded
Pipe Nipples and Pipe

testString

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

testString

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Low-Pressure Brass and Bronze Threaded Pipe Fittings

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

Standard-Wall Brass Threaded
Pipe Nipples and Pipe

Typically used with low-pressure brass and bronze threaded pipe fittings.

Low-Pressure Brass and
Bronze Threaded Pipe Flanges

testString

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.
