How to install the Philmac CTS Compression Fitting

Overview / Why Choose This Product

Philmac CTS Compression Couplings are engineered to provide a dependable, quick‑install solution for CTS HDPE water service tubing and Municipex pipe. Built around Slide & Tighten™ technology, these fittings eliminate the need for pipe preparation or disassembly, simplifying installation and reducing on‑site labor time. Installers simply cut the pipe square, insert it until resistance, and tighten the nut to the flange. Fast, precise, and tool‑efficient.

Rated to 230 psi, the CTS Compression range provides a high‑integrity mechanical joint resistant to corrosion and free from lead, making it suitable for potable water and long‑term service environments. Its compact body design allows easy installation in trenches, confined spaces, or fixed‑point systems where maneuverability is limited. With components retained inside the fitting body and advanced thermoplastic construction, the system is engineered for durability, reliability, and consistent sealing over decades of service.
