King Protect – R for LPG / Acetylene Gas is a regulator-mounted flashback arrester designed to stop backfire right at the regulator end. Engineered with a flame arrestor, temperature-sensitive cut-off valve, and a spring-loaded non-return valve, it offers complete multi-layered protection. This device ensures safe gas flow, prevents dangerous reverse gas movement, and automatically cuts off during sustained flashbacks—making it ideal for industrial welding and cutting setups.
