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.

Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

Typically used with low-pressure stainless steel threaded pipe fittings.

Standard-Wall Stainless Steel Threaded
Pipe Nipples and Pipe with Sealant

Typically used with low-pressure stainless steel threaded pipe fittings.

Standard-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

Standard-Wall Steel Threaded Pipe Nipples and Pipe

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

Standard-Wall Steel Threaded
Pipe Nipple and Pipe Assortments

Assortments contain threaded pipe in various lengths.

Standard-Wall Steel Pipe Nipples and Pipe
with Right-Hand and Left-Hand Threads

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

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

Standard-Wall Galvanized Steel Pipe Nipples
and Pipe for Joining Dissimilar Metals

A plastic sleeve prevents destructive corrosion when connecting different metals.

Standard-Wall Galvanized Steel Threaded
Pipe Nipple and Pipe Assortments

Assortments contain threaded pipe in various lengths.

Standard-Wall Steel Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Standard-Wall Grooved-End
Steel Pipe Nipples and Pipe

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

Standard-Wall Brass Threaded Pipe Nipples and Pipe

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

Standard-Wall Brass Threaded
Pipe Nipples and Pipe with Sealant

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

Standard-Wall Chrome-Plated Brass
Threaded Pipe Nipples and Pipe

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

Standard-Wall Brass Unthreaded Pipe

Typically used with brass and bronze unthreaded pipe fittings.

Standard-Wall Aluminum
Threaded Pipe Nipples and Pipe

Typically used with low-pressure aluminum threaded pipe fittings.

Standard-Wall Aluminum
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall aluminum unthreaded pipe fittings.

Standard-Wall Copper-Nickel
Threaded Pipe Nipples and Pipe

Also called close nipples, these Schedule 40 nipples are threaded on both ends to the center.

Plastic Pipe and Pipe Fittings

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings in low- to medium-pressure applications up to 810 psi. It is typically used in residential and commercial plumbing and water supply applications.

UV-Resistant Standard-Wall PVC Pipe for Water

This Schedule 40 pipe is typically used in low-pressure residential and commercial plumbing and water supply applications. It can handle pressures up to 300 psi. Suitable for outdoor environments, it contains an additive that protects against the damaging effects of ultraviolet light. Connect to UV-resistant PVC pipe fittings.

Drain, Waste, and Vent ABS Pipe for Chemicals

This pipe is an economical choice for gravity-flow chemical waste systems. Pipe is ABS plastic, which has excellent strength and impact resistance and good chemical resistance.
