WFI1A09982 Inserta Tee FatBoy - 4 in main x 10-12 in lat (...)

The ADS® 4P26FB10‑12P35 Inserta Tee FatBoy is designed to provide a watertight, air-testable lateral connection by tapping a 10–12″ SDR 35 or SDR 26 PVC lateral into a 4″ mains line. It uses a three-component assembly—PVC hub, EPDM rubber sleeve, and stainless steel clamp—to create a compression seal, eliminating the need for adhesives, grout, or gaskets. Core-drilled into existing pipelines, this system is ideal for trenchless installations, pipe bursting, manhole taps, and rehabilitation projects. Its robust design ensures long-term durability and performance in both new and retrofit sewer or drainage systems.

Three‑piece compression‑fit insert tee for creating 10–12″ lateral taps on 4″ SDR 35/26 PVC mains—no glue or grout required.
