National Diversified Sales 4P09 4" White Hub x Hub x Hub PVC S&D Sanitary Tee adds a 90° sweep to a 4 in. sewer and drain (S&D) pipe run. The San Tee, or Sweep Tee, is installed for less turbulent flow and easier clean out of the pipeline.

This tee is used to add an intersection to the pipeline, connecting three pipes of the same type and diameter size. The drain fitting is made of polyvinyl chloride (PVC) for Hub X Hub X Hub solvent-weld connections. Meets applicable ASTM standards. For use in non-pressurized underground sewer and drainage applications; maximum working pressure of 5 psi.
