The JG Speedfit 15mm polybutylene barrier pipe offers a highly flexible 50-metre plumbing solution formulated for seamless integration into extensive hot and cold water networks. Manufactured in the UK this continuous coil features a specialised layflat structural memory which prevents the material from violently retracting when unspooled making joist cabling and long-run alignments exceptionally straightforward. The lightweight 3.53kg coil drastically reduces handling fatigue on large-scale domestic first fixes while the pipe's low thermal conductivity ensures the exterior remains safe to touch even when transporting high-temperature domestic hot water.

Constructed using an advanced five-layer extrusion process the core integrates a dedicated oxygen barrier that halts gaseous ingress through the pipe wall. This critical layer prevents the oxygenation of primary heating fluid significantly lowering the risk of subsequent magnetite corrosion attacking vulnerable metal radiators and boiler heat exchangers. Completely WRAS approved and fully compliant with BS 7291 and KM 39767 standards this polybutylene conduit must always be utilised alongside official JG Speedfit pipe inserts to guarantee absolute joint integrity under pressurised conditions.

Q: Does this coil easily retain its shape when unrolled?
A: The engineered layflat composition ensures the pipe remains perfectly straight once dispensed without aggressively coiling back.

Q: How does the barrier layer protect the wider heating system?
A: The central polymer layer physically blocks oxygen molecules from entering the fluid thereby halting internal metal corrosion.

Q: Is this product suitable for hard water territories?
A: Yes the smooth polybutylene interior successfully resists scale accumulation in both hard and soft water regions.

Q: What specific preparation is required before securing a fitting?
A: Installers must insert a rigid JG Speedfit pipe stiffener into the cut end to support the internal diameter against compression.
