About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation. Fittings are plastic for good corrosion resistance. They meet ASTM specifications and testing requirements for material quality.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

CPVC Pipe Fittings for Hot Water

Made of CPVC, these fittings can handle high temperatures. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. They also have good corrosion resistance. These fittings are comparable to Corzan. Some meet ASTM D1784 specifications and testing requirements for material quality.

Fittings for drinking water meet NSF/ANSI Standard 61.

Schedule 80 fittings have thick, strong walls for heavy duty, industrial applications.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Saddle-tap adapters allow you to tap into an existing pipeline. They have wraparound clamps that provide nearly 360° contact with pipe; as the clamps are tightened, pressure is uniformly distributed around the pipe for maximum support. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole and tighten the clamps.
