The OATEY COMPANY 43795 is a 4-inch by 4-inch PVC saddle tee kit designed for branch connections on existing PVC drain, waste, and vent (DWV) pipe systems. The saddle tee design allows a plumber to add a new branch outlet to an in-place run of pipe without cutting out a full section and installing a traditional tee fitting. The kit includes the saddle components needed to make a secure, solvent-welded connection. It is suited for residential and light commercial plumbing applications where adding a new line to an existing 4-inch PVC main is required.
This saddle tee kit is used when tapping into an existing 4-inch PVC DWV main to create a new branch for a drain or vent line. Typical scenarios include adding a new fixture drain, extending a vent stack, or connecting auxiliary drain lines in a retrofit or remodel situation. It is installed by licensed plumbers working on below-grade or above-grade interior drain systems. The 4-inch inlet and 4-inch outlet sizing makes it appropriate for main drain stack applications in residential construction and renovation projects.
Designed as an OEM-style replacement and add-on fitting for 4-inch schedule 40 PVC DWV pipe systems used in residential and light commercial plumbing installations.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off or isolate flow in the existing pipe before cutting or drilling the saddle port opening. Clean and dry all mating surfaces thoroughly before applying PVC solvent cement to ensure a proper bond. Do not pressure-test the connection until the solvent cement has fully cured per the cement manufacturer's cure time guidelines.
