WFI1A09983 Inserta Tee FatBoy 4 in IPS Main x 15-18 in S (...)

The ADS® 4P26FB15‑18P35 Inserta Tee FatBoy is a durable, field-installed lateral fitting that enables a watertight, air-testable joint between a 4″ IPS mainline and a 15–18″ SDR 35/26 PVC lateral. Featuring a three-component assembly—PVC hub, EPDM rubber sleeve, and stainless-steel clamp—it compresses to create a robust seal without the need for adhesives, grout, or gaskets. This fitting is ideal for trenchless applications such as core-drilling, pipe bursting, and lateral taps in sewer and drainage systems, offering high-performance durability in both new construction and rehabilitation projects
