The FlexiGas 40mm Flexible Gas Pipe (DN40) – 200m Spool is a corrugated stainless steel (CSST) gas pipe that bends easily by hand, letting you run long continuous lengths and install up to 4x faster than copper or rigid steel. Certified under the BSI Kitemark scheme (KM 598726) and manufactured to BS/EN 15266, it can even be buried in screed or the ground without additional protection.

✔ BSI Kitemark certified  |  ✔ EN 1775 Annex A & B fire tested  |  ✔ Metre marked for easy measuring  |  ✔ Free roll of silicone tape included

Key Features

• On-demand tubing for project work — pair with the FlexiGas spool roller (SPL-01) to unroll on site, measure exactly and cut with zero wastage.
• Bends by hand — the corrugations flex without losing the strength of a steel tube, so long continuous runs need far fewer joints and potential leak points.
• Fast, flame-free installation — no soldering, sealants or specialist tools; patented FlexiGas™ fittings create a 100% metal-to-metal seal in seconds.
• Tough yellow jacket — fire-retardant polyethylene cover (B-s1 d0), UV resistant and suitable for direct burial in screed or soil.
• 25+ DN40 fitting types — the UK's largest CSST fitting range in dezincification-resistant brass, including copper connections up to 54mm.
• FG Bond™ ready — pair with the integrated earthing terminal (certified to BS 951:2009). Where a sleeve is required, add sleeving or choose pre-sleeved FlexiGas DS.
