The OATEY COMPANY 43791 is a 4-inch by 2-inch PVC saddle tee kit designed for making branch connections on existing PVC drain lines without cutting out a full section of pipe. The kit provides a clamp-on saddle fitting that seats over the main 4-inch pipe and accepts a 2-inch branch outlet, allowing a new drain line to be tied in with minimal disruption to the existing system. Plumbers and drain service professionals use this fitting in both new construction and retrofit applications where access and pipe continuity are critical. The unit ships as an each and is packaged six per case.
The 43791 saddle tee kit is suited for residential and light commercial drain, waste, and vent (DWV) plumbing applications. It is typically installed on 4-inch PVC main lines in below-slab, in-wall, or crawl-space drainage systems where a 2-inch branch connection is needed for a lavatory, washing machine standpipe, floor drain, or similar fixture drain tie-in. Its saddle-style design makes it a practical option when cutting and re-joining the main line is not desirable or practical.
Designed as an OEM-style replacement and new-installation fitting for 4-inch PVC DWV main lines requiring a 2-inch branch outlet connection.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off water service and ensure the existing drain line is clear and dry before fitting placement. Follow the manufacturer instructions for proper solvent-weld cement application and clamp torque sequence. Do not use on pressurized water supply lines.
