Thick-Wall Plastic Pipe Flanges for Water
- For Use With: Drinking Water, Water
- Class: 150
- Maximum Temperature: 140° F
- Specifications Met: ASTM D1784, NSF/ANSI Standard 61 for Drinking Water
- Pipe Nipples and Pipe: Use Schedule 80 PVC Plastic
- Fittings: Use Schedule 80 PVC Plastic
Also known as Class 150 flanges, these flanges have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They meet NSF/ANSI Standard 61 for drinking water. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are PVC, which has good corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.
For technical drawings and 3-D models, click on a part number.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Rotating flanges are also known as Van Stone flanges; they swivel for easy bolt hole alignment.

Aboveground Standard-Wall PVC Pipe
Flanges for Drain, Waste, and Vent
- For Use With: Water
- Max. Temperature: 140° F
- Specifications Met: ASTM D1784, ASTM D2665
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
- Fittings: Use Schedule 40 PVC Plastic
Also known as Schedule 40 flanges, these are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. They are PVC for good corrosion resistance. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld). Flanges meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.
