Plastic Pipe and Pipe Fittings for Water

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.

High-Pressure Barbed Plastic Pipe Fittings for Water

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

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.

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.

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.

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.

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.

CPVC Pipe Fittings for Hot Water

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

UV-Resistant Standard-Wall PVC Pipe Fittings for Water

Connect these fittings to UV-resistant PVC pipe. Designed for outdoor use, they contain an additive that protects against the damaging effects of ultraviolet light. Fittings are typically used in low-pressure residential and commercial plumbing and water supply applications up to 300 psi.

Low-Pressure Barbed Plastic Pipe Fittings for Water

Use for pressures up to 60 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

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.

Plastic Pipe and Pipe Fittings for Drain, Waste, and Vent

Underground Snap-Lock Polyethylene
Pipe Fittings for Drain, Waste, and Vent

The snap-together design allows you to quickly connect these fittings to pipe with no cement required. Fittings are typically used in gravity-flow drainage applications.

Underground PVC Pipe Fittings
for Drain, Waste, and Vent

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Underground Snap-Lock Polyethylene
Pipe for Drain, Waste, and Vent

Pipe has a snap-together design that allows you to quickly connect to fittings with no cement required. It is typically used in gravity-flow drainage applications.

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.
