Drain, Waste, and Vent ABS Pipe Flanges for Chemicals

These Schedule 40 flanges are an economical choice for gravity-flow chemical waste systems. Flanges are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Bolt two same-size flanges together with a gasket (not included) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with ABS cement (also known as solvent weld). They meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.

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

Floor Drain Cleanouts

Create an access point to inspect and clean a floor drain pipeline. The cover on these cleanouts can be adjusted up or down to sit flush with the finished floor. An ABS cleanout plug underneath the cover prevents debris from entering and sewer gases from exiting the system. These cleanouts are compatible with Schedule 40 PVC pipe for gravity-flow drain, waste, and vent applications. Attach to your unthreaded drain pipe with a PVC primer and cement (also known as solvent weld).

Toilet Mounting Flanges


Style D	Style E

Repair or replace the connection between your toilet and drainage system.

Style E—Style E allow you to offset the flange face up to _3/4" from the base in any direction, so you can reposition a toilet without modifying your drain. The base has a rubber gasket to seal your pipe.

Adjustment Bolts—Flanges with adjustment bolts can be installed up to 3" above the top of your pipe, so you can match the height of finished floors. When you tighten the bolts, a compression joint expands to press against the walls of the pipe, holding it in place.

Urinal Flanges

Connect a urinal to your drainage system. These mounting flanges come with a gasket and mounting fasteners, so they’re ready to install. If you’re attaching them to your existing drain, choose the same material.

ABS—ABS is more impact resistant than PVC.
