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.

Pipe Fittings for Water

Connect these fittings to standard-wall plastic pipe for use in low- to medium-pressure applications up to 750 psi.They are the industry standard for residential and commercial plumbing and water supply applications.
