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.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

High-Pressure Galvanized
Steel Threaded Pipe Fittings

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

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

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

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.

Extreme-Pressure Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications.
