Not only are we confident that you are installing the highest quality gas products, where materials and workmanship are never compromised, but many of our products include innovative and patented features found exclusively on GFS branded products. Install with confidence where you see the GFS brand mark including:

  • GFS CSST – offering a patented unique “Push and Seal” fitting system, the only push fit system available to any CSST system in the UK. GFS CSST pipe annealing process offers means that we can offer flexible long runs without the need for any hot works and fewer joints.

    • Extension of existing gas installations
  • GFS PLUS – the only genuine pipe in pipe CSST system in the UK, where installation criteria states CSST pipe must be sleeved, GFS can provide this pre sleeved version.
