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 Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings in low- to medium-pressure applications up to 750 psi. It is typically used in residential and commercial plumbing and water supply applications.

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.

Extra-Thick-Wall
Plastic Pipe for Water

Extra-thick Schedule 120 walls give this pipe excellent strength in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use in high-pressure applications up to 1,000 psi. They connect to thick-wall plastic pipe fittings.

UV-Resistant Thick-Wall
PVC Pipe for Water

With thicker, stronger walls than standard-wall pipe, this Schedule 80 pipe can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Use for pressures up to 550 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.

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.

Underground PVC Pipe
for Drain, Waste, and Vent

This pipe has thinner walls than Schedule 40 pipe, so it’s lighter in weight and has more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines.
