The CG Overflow Regulator features an overflow level indicator for visual gas level monitoring and leak testing. All Cadac cylinder regulators come standard with a crimped 85 cm hose and quick release (QR) fittings for enhanced safety. The Excess Flow Valve (EFV) automatically cuts off 90% of the gas flow if the hose is compromised, and the QR fitting stops gas flow if disconnected from the BBQ.
