Useful Info:

Gastite is a corrugated stainless steel tubing (CSST) lightweight alternative to copper gas pipe.

With its flexible design, Gastite can cut installation time by up to 50%, when compared to a traditional gas pipework system. This is supported by the reduced number of fittings and joins required, as the pipe can be bent by hand and cut with simple cutters.
