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 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 for Drinking Water

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

Thick-Wall Plastic Pipe for Water

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Thick-Wall Plastic Pipe Flanges for Water

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

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.

Semi-Flexible Plastic Pipe for Water

Connect to barbed plastic pipe fittings with a clamp. Pipe isn't as bendable as soft tubing, but can still bend around objects, resulting in fewer connection points in your line. Fewer connection points not only shortens installation time, but also allows for smoother flow through the line.

CPVC Pipe for Hot Water

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

CPVC Pipe Fittings for Hot Water

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications up to 200° F.

CPVC Pipe Flanges for Hot Water

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Tubing and Tube Fittings

Medium-Pressure Copper Tubing for Drinking Water

This Type L tubing has thicker walls than Type M tubing. It withstands pressures up to 1,500 psi.

Low-Pressure Copper Tubing for Drinking Water

This Type M tubing has the thinnest walls of all our copper tubing for drinking water. It withstands pressures up to 980 psi.

High-Pressure Copper Tubing for Drinking Water

This Type K tubing has the thickest walls of all our copper tubing for drinking water. It withstands pressures up to 1,900 psi.

Hard Plastic Tubing for Drinking Water

This tubing has hard walls like copper tubing, but is lighter in weight and easier to install. It connects to fittings with no heat or soldering required. Tubing meets NSF/ANSI Standard 61 for drinking water.
