Flexible stainless-steel gas pipework

Eliminate the elbows.

Flexigas CSST routes gas pipework around obstacles in one continuous run, with fewer joints, no hot works at the seal, and far less time on site than rigid copper.

Installer-first

Less joining. More doing.

Flexigas flexes around joists, through ceilings and across awkward routes copper has to be soldered around. Fewer joints means fewer leak points and less time on site. No soldering, no hot works at the seal, just two spanners.
