For enhanced safety, this Cadac Propane Clip-On cylinder regulator is equipped with a 2-meter hose that is securely crimped to the regulator at the factory. It features an important safety mechanism known as the Excess Flow Valve (EFV), which comes standard. This automatic safety feature shuts off 90% of the gas flow if the hose is damaged. Additionally, the regulator includes a convenient clip-on attachment for secure usage and comes with a hand-tightening clamp for easy installation.
