Philmac UTC Transition Coupling
The Philmac UTC Transition Coupling is a versatile range of mechanical compression fittings designed to deliver maximum flexibility when connecting pipes made from different materials.
Each UTC Transition fitting connects directly to a wide range of pipe types without modification, including PVC, copper, galvanized steel, ABS, lead, stainless steel, and polyethylene. With each size accommodating a broad diameter range, the UTC provides a truly universal connection solution for plumbing, irrigation, and water transfer applications.
The UTC Transition Coupling incorporates Philmac’s proven Slide and Tighten™ technology, ensuring fast, reliable installation. Simply mark the pipe at the flange on the fitting body to confirm insertion depth, slide the pipe into place, and tighten the nut—no special tools required.
Manufactured from lightweight, high‑performance thermoplastic materials, the UTC Transition is engineered for long-term durability. Its construction offers excellent impact resistance along with UV, chemical, and corrosion protection, making it suitable for demanding environments. With a pressure rating up to 1250 kPa (approx. 180 psi), the UTC meets the performance requirements of high‑pressure systems commonly used in the United States.
