Overview / Why Choose This Product
Philmac SIDR Compression Couplings are designed to provide fast, secure, and repeatable connections for SIDR HDPE pipe, making them a preferred solution for agricultural, rural, and potable‑water applications across North America. The system leverages Philmac’s advanced 3G compression technology, which allows installers to achieve a reliable joint without pipe heating, barbed insert tools, or mechanical clamps. Dedicated inserts tap directly into the pipe with minimal effort, and the nut tightens to the visual stop on the fitting body, ensuring precise installation every time.
These couplings deliver a 230 psi pressure rating, meeting the needs of demanding cold‑water systems used in irrigation, livestock watering, pump systems, and community water supplies. With a 50‑year+ design life and corrosion‑resistant materials, they are engineered to perform in rugged field conditions and remote environments. Key Features
3G Compression Technology – Simple insert‑and‑tighten assembly with reliable sealing.
Tap‑in inserts for each end – Avoids pipe manipulation during installation.
Rated to 230 psi – Suitable for high‑pressure rural and irrigation systems.
Fits all SIDR pipes up to SIDR 15 – One coupling covers multiple pipe standards.
Potable‑water approved – NSF / CSA B137.1compliant.
