Polypipe PolyPlumb Polybutylene Barrier Pipe – 15mm x 50m PB Coil | PB5015B (Grey)

The Polypipe PolyPlumb 15mm x 50m Polybutylene Barrier Pipe is designed for hot and cold water and heating systems in domestic properties. Supplied in a 50-metre coil, this flexible pipe reduces installation time and the number of joints required, offering long-term durability and efficiency.

With “Plumb Straight” technology, the coil remains straight when unrolled for easier handling. PolyPlumb pipe is lightweight, push-fit compatible (no naked flames required), and resistant to freezing temperatures. Its plastic construction prevents scale build-up, corrosion, and burst pipes, while reducing noise and heat loss compared with rigid metal systems.

Ideal for radiator systems, underfloor heating, and potable water applications, this pipe is suitable for both hard and soft water areas. WRAS and BBA approved, it comes with a 25-year manufacturer guarantee when installed correctly under normal domestic operation.
