Polypipe PolyPlumb Polybutylene Barrier Pipe – 22mm x 50m PB Coil | PB5022B (Grey)

The Polypipe PolyPlumb 22mm x 50m Polybutylene Barrier Pipe is built for hot and cold water, central heating, and underfloor heating systems in domestic properties. Supplied in a 50‑metre coil, this pipe offers flexibility and ease of installation with reduced joint requirements, helping streamline plumbing and heating installs.

With its multilayer barrier construction, the pipe resists scale build-up and corrosion — avoiding frequent maintenance and reducing risk of leaks or bursts associated with rigid metal systems. The plastic construction results in quieter system operation and reduced heat loss. The coil remains straight when unrolled for easier handling on site.

This PolyPlumb pipe is WRAS and BBA compliant (when used with compatible fittings and systems) and suitable for use in both hard and soft water areas. It’s ideal for radiator circuits, underfloor heating, and potable water distribution — offering a versatile solution for a variety of plumbing and heating needs.
