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.

Thick-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

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

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 Steel Threaded Pipe Nipples and Pipe

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

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.

Thick-Wall Steel Threaded Pipe Nipples and Pipe

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

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.

Extra-Thick-Wall Steel Threaded Pipe Nipples and Pipe

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

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.

Super-Thick-Wall Steel Threaded Pipe Nipples and Pipe

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

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 Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

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.

High-Pressure Brass Threaded Pipe Nipples and Pipe

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

High-Pressure Brass Threaded
Pipe Nipples and Pipe with Sealant

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

High-Pressure Brass Threaded Pipe
Nipples and Pipe for Drinking Water

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

High-Pressure Plated Brass
Threaded Pipe Nipples and Pipe

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

Thick-Wall Brass Threaded Pipe Nipples and Pipe

Typically used with medium-pressure brass and bronze threaded 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.

Thick-Wall Aluminum Threaded Pipe Nipples and Pipe

Typically used with high-pressure aluminum threaded pipe fittings.

Plastic Pipe and Pipe Fittings for Chemicals

High-Temperature PTFE Pipe
Nipples and Pipe for Chemicals

This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It is commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Flame-Retardant PVDF Pipe
Nipples and Pipe for Chemicals

Pipe meets UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. It is made of PVDF, which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.
