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 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 Steel Threaded Pipe Flanges

With better strength than our low-pressure steel flanges, these are for use in medium-pressure applications.

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.

Medium-Pressure Galvanized
Steel Threaded Pipe Flanges

Also known as Pressure Class 300 flanges, these medium-pressure flanges have a galvanized finish for fair corrosion resistance.

Threaded Gradual On/Off Valves

Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.

Threaded Gradual On/Off Valves for Drinking Water

Also known as gate valves, these valves open and close gradually to prevent damage to your drinking water system from sudden starts and stops in flow. They meet NSF/ANSI 61, so they're safe to use with drinking water.
