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.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as 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.

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.
