Aboveground Standard-Wall PVC Pipe Fittings 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
- Flanges: Use Schedule 40 PVC Plastic
These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. Fittings are PVC, which has good corrosion resistance. They meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
Fittings with a compression end are also known as slip-joint fittings. Insert the tube into the compression end and turn the nut until hand tight. Since you don't have to wait for cement to dry, they are quicker to install than socket-connect fittings.

Fittings with a compression end are also known as slip-joint fittings. Insert the tube into the compression end and turn the nut until hand tight. Since you don't have to wait for cement to dry, they are quicker to install than socket-connect fittings.
270° bend fittings are also known as P-traps. They separate into three pieces, so you can access your line.
Offset tees are also known as sanitary tees and eccentric tees. They have an offset branch so the line can drain. Use them for applications that require frequent cleaning and inspecting.
Offset tees are also known as sanitary tees and eccentric tees. They have an offset branch so the line can drain. Use them for applications that require frequent cleaning and inspecting. Long offset tees are also known as long radius wyes.
Inline tees are also known as branch tees. Offset tees are also known as sanitary tees and eccentric tees. They have an offset branch so the line can drain. Use them for applications that require frequent cleaning and inspecting.
To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
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.
