Drain, Waste, and Vent Iron Pipe Fittings

Use these fittings in gravity-flow applications both above and below ground. They are also known as no-hub pipe fittings and soil pipe fittings. To connect, place the end of the fitting against your pipe or another fitting and connect with a low-pressure clamp-on connector (sold separately). The clamp-on connector is also known as a no-hub coupling. Fittings are for use in noncorrosive environments.

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–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. 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).

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.

CPVC Pipe Fittings for Hot Water

Made of CPVC, these fittings can handle high temperatures up to 200° F. 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.

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.

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

For Use With: Water
Specifications Met: ASTM F667, Soil Conservation Service Standards

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. Made of high-density polyethylene (HDPE), they stand up to freeze/thaw cycles and resist corrosion and stress cracking. Fittings meet ASTM F667 specifications and testing requirements for material quality as well as soil conservation service (SCS) standards for use in underground drain lines.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas. Do not expose fittings to direct sunlight.
