Is 15mm Flexigas a flexible gas hose?

No. It is part of the Flexigas CSST system for fixed gas pipework. It should not be treated as a loose appliance hose.

What should I check before using 15mm Flexigas?

Check appliance demand, gas type, total route length, equivalent fittings, pressure drop, installation environment and the current Flexigas installation manual.

Use Flexigas tubing and fittings as a system. Do not mix Flexigas CSST or fittings with other manufacturers' CSST systems.
