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.

Thick-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

Thick-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Thick-Wall Stainless Steel Unthreaded Pipe

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

Stainless Steel Bleed Rings

Create an access point in systems where corrosion is a concern. Made of stainless steel, these bleed rings resist rusting.

Iron and Steel Pipe and Pipe Fittings

Medium-Pressure Iron and
Steel Threaded Pipe Fittings

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Medium-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Thick-Wall Galvanized Iron and Steel
Threaded Pipe Nipples and Pipe

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

Thick-Wall Steel Unthreaded Pipe Nipples and Pipe

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Steel Bleed Rings

Access the inside of lines, so you can vent pressure, drain liquid, or take samples. Made of black-coated steel, these bleed rings should be used in dry environments to prevent rusting.
