The Polyplumb 22mm Barrier Pipe is a robust, lightweight polybutylene plumbing solution specifically engineered for reliable central heating and hot water hydraulic installations. Supplied in convenient 3-metre straight lengths, this highly flexible grey pipe incorporates a protective internal oxygen barrier that actively prevents the ingress of air into the system fluid, aggressively protecting metallic components like boilers, valves, and radiators from internal corrosion. Weighing just 3.75kg per length, it allows plumbing installers to easily navigate complex floor joist layouts and tight building voids without the need for extensive traditional jointing techniques.
Manufactured to strict industry tolerances by Polypipe, this WRAS and BBA-approved barrier pipe is Kitemarked to BS 7291 Class S standards, ensuring rigorous performance under extreme thermal stress. It is fully compatible with standard Polyplumb demountable push-fit fittings, which lock tight to prevent accidental separation while remaining adjustable with a dedicated release tool. Designed to integrate seamlessly with both modern plastic manifolds and traditional copper pipework, this 22mm diameter extrusion delivers a highly secure, tamper-resistant hydraulic circuit for demanding residential plumbing infrastructure projects.
Q: What material is this barrier pipe made from?
A: It is extruded from durable, high-quality grey polybutylene plastic.
Q: Does the pipe prevent oxygen ingress?
A: Yes, the built-in barrier layer stops oxygen permeation to prevent system corrosion.
Q: What certifications does this plumbing pipe hold?
A: The product is fully WRAS approved, BBA certified, and Kitemarked to BS 7291.
Q: Can it be connected to existing copper pipework?
A: It integrates seamlessly with copper systems when used with compatible push-fit fittings.
