It’s intended for use in gas distribution runs where flexibility, corrosion resistance, and long runs are needed. The hose measures approximately 0.66\" (17 mm) inner diameter and 0.8\" (22 mm) outer diameter, and arrives fitted with male brass connectors on both ends. It is CSA tested to meet North American standards, but it should be installed according to local codes and by qualified professionals.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this CSST hose make installations easier?\u003c\/h3\u003e\n\u003cp\u003eThe corrugated profile and flexible stainless core let you bend and route the line without many rigid fittings, reducing time and potential leak points. The pre-attached male brass fittings simplify connections to standard threaded gas fittings.
