FlexiGas DS Contractor Kit Range
FlexiGas DS 40mm Contractor Kit – 10m with 2x Copper Unions
A complete pre-sleeved flexible gas pipe kit featuring a 10-metre DN40 CSST coil, two copper compression unions and a free roll of silicone tape for professional gas installations.
The FlexiGas DS 40mm Contractor Kit – 10m with 2x Copper Unions provides a convenient solution for commercial gas engineers installing 40mm gas pipework. The kit includes a 10-metre coil of double-sleeved corrugated stainless steel tubing (CSST), two FlexiGas-to-copper compression unions and a roll of yellow silicone tape.
Featuring an integrated V0 fire-rated sleeve, the FlexiGas DS-40 is designed for routing through solid walls, floors, screed, soil and unventilated voids, subject to applicable installation requirements. Its flexible construction allows the pipe to bend by hand, helping installers create continuous runs with fewer joints and potentially reduce installation time compared with conventional copper pipework.
Manufactured to BS/EN 15266 and certified under the BSI Kitemark scheme (KM 598726), this DN40 contractor kit has a stated maximum operating pressure of 0.5 bar. The included compression unions connect the FlexiGas pipe directly to compatible copper pipework, making the kit suitable for professional installations requiring copper connections at both ends.

Key Features
1. Double-Sleeved CSST Pipe
Features an inner gas-carrying corrugated stainless steel pipe within an integrated V0 fire-rated sleeve. The pre-sleeved design helps avoid the need to add separate sleeving on site where the system is suitable for the installation.
2. Designed for Multiple Installation Scenarios
Designed for specified routes through solid walls, floors, screed, soil and unventilated voids. Install in accordance with the manufacturer's instructions and applicable gas installation standards.
3. Flexible and Fast to Install
The pipe bends by hand to help create continuous runs with fewer joints. The supplied product information states that installation can be up to four times faster than copper, helping reduce installation time on suitable projects.
4. Copper Compression Unions Included
Two FlexiGas-to-copper compression unions are supplied for connecting the flexible gas pipe to compatible copper pipework at both ends. The fittings are made from dezincification-resistant brass and feature a metal-to-metal sealing design.
5. Certified for Professional Applications
The product information specifies BSI Kitemark KM 598726 certification and manufacture to BS/EN 15266, with EN 1775 Annex A and B fire testing stated for the system.
