The FlexiGas 22mm Flexible Gas Pipe (DN22) – 50m Box 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  |  ✔ Direct burial in screed or ground  |  ✔ Free roll of silicone tape included

Key Features

• 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, no reaction to fire), UV resistant and suitable for direct burial in screed or soil.
• 130+ FGLink™ fittings — dezincification-resistant brass, including 55+ copper connection fittings for easy integration with existing copper pipework.
• FG Bond™ ready — pair with the integrated earthing terminal (certified to BS 951:2009) for quick electrical bonding.
• Easy on site — metre-marked tubing and 1x free roll of silicone tape included. Where a sleeve is required (solid walls, unvented voids), add sleeving or choose pre-sleeved FlexiGas DS.
