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.
