Polypipe PolyPlumb Polybutylene Barrier Pipe – 28mm x 50m PB Coil | PB5028B (Grey)

The Polypipe PolyPlumb 28mm x 50m Polybutylene Barrier Pipe is suitable for domestic hot and cold water systems, central heating, and underfloor heating installations. Supplied in a 50-metre coil, its flexible design allows for easier routing around obstacles, reducing the number of joints and speeding up installation.

With “Plumb Straight” technology, the coil maintains its shape when unrolled for easier handling. Its plastic construction prevents scale build-up, corrosion, and burst risks while offering quieter operation and reduced heat loss compared with rigid metal pipes. The pipe is lightweight, push-fit compatible (no naked flames required), and resistant to freezing temperatures.

This PolyPlumb pipe is WRAS and BBA compliant when used with compatible fittings and is suitable for both hard and soft water areas. It provides a reliable solution for radiator circuits, underfloor heating, and potable water distribution in domestic properties.
