Double Sleeve Flexigas Installer / Contractor Kits
Flexigas DS is a premium double-sleeved gas pipe solution designed for both domestic and commercial gas installations. Built with high-quality 316L marine-grade corrugated stainless steel tubing (CSST), it delivers exceptional flexibility, durability, and corrosion resistance.
The first layer features CSST with a tough yellow polyethylene cover, while the second layer adds corrugated sleeving with an external polyethylene coating for enhanced protection and compliance. Unlike traditional copper or steel pipework, Flexigas offers a faster, smarter, and more efficient installation solution for professional plumbers.
Key Benefits:
- Double-sleeved design for maximum protection straight out of the box
- Suitable for 100% of installation scenarios with no extra sleeving required on-site
- Saves installation time on complex domestic and commercial projects
- Manufactured from 316L marine-grade stainless steel for superior corrosion resistance
- Flexible alternative to copper and steel gas piping
- Compliant with BS 6891 and IGEM standards
For simpler projects requiring minimal sleeving, standard Flexigas with additional sleeving may offer a more cost-effective solution.
