General description Polyplumb barrier pipe is a flexible alternative to copper tube, suitable for both hard and soft water areas. It incorporates an oxygen diffusion barrier to prevent the ingress of oxygen into the system. Manufactured to the highest standards, this pipe is ideal for underfloor heating, radiator central heating systems, and domestic hot and cold (potable) water services. The PolyPlumb system is a traditional push-fit plumbing solution that has proven robust and reliable over time.
