Overview / Why Choose This Product
Philmac IPS‑OD Large Bore Compression Couplings are purpose‑built for large‑diameter 2″ and 3″ IPS‑OD HDPE pipe, delivering strong, reliable, and repeatable mechanical joints with minimal installation effort. Using Slide & Tighten™ technology, installers can assemble couplers quickly with a simple insert‑and‑tighten method that requires no pipe preparation and no force to push the pipe past the seal. This reduces labor time and increases installation consistency across field conditions.
The IPS-OD Large Bore Couplings are engineered with a 230 psi pressure rating, ensuring suitability for demanding cold‑water systems used by municipalities, rural districts, and irrigation operators. Their robust thermoplastic construction is corrosion‑resistant, lightweight, and designed for long‑term performance in buried or above‑ground environments. The fittings also use a visual stop—the flange on the fitting body—to ensure correct tightening and prevent over‑torqueing. With components retained inside the nut assembly, installers benefit from a clean, efficient workflow and less risk of losing parts during trench installations.
