Polypipe PolyPlumb Polybutylene Barrier Pipe – 22mm x 25m PB Coil | PB2522B (Grey)

The Polypipe PolyPlumb 22mm x 25m Polybutylene Barrier Pipe is designed for use in domestic hot and cold water systems, radiator circuits, and underfloor heating installations. Supplied in a 25‑metre coil, its flexibility allows it to be cabled around obstructions, reducing the number of joints and simplifying installation.

With “Plumb Straight” technology, the coil remains straight when unrolled, making handling on site easier. The lightweight, push-fit pipe requires no naked flames during installation and is resistant to freezing temperatures, ensuring long-term durability. Its plastic construction prevents scale build-up, corrosion, and burst risks, while reducing noise and heat loss compared with rigid metal pipes.

Suitable for use in both hard and soft water areas, this pipe is WRAS and BBA approved. Polypipe provides a manufacturer guarantee against defects when installed correctly under normal domestic conditions.
