Bes Yapi started manufacturing products under the Gas Flex Systems (GFS) brand in 2004. Established in 1996, Bes Yapi are one of the leading manufacturers. We produce high-quality, innovative stainless steel gas and flexible metal hoses. We now export GFS products to over 25 countries worldwide, on 5 continents! The GFS UK office and warehousing is now based in Cheshunt, Hertfordshire. All our products are available in the UK via our approved distribution network.
GFS CSST, manufactured to BS EN 15266, is the safest, most efficient and fastest CSST system in the market.
