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 stainless-steel 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. Key Features 1. Stainless-steel flame arrestor with large surface area to instantly extinguish flashbacks from any direction 2. Temperature-sensitive cut-off valve that shuts down sustained flashbacks before internal temperatures reach danger levels 3. Spring-loaded non-return valve to stop both slow and sudden reverse gas flow 4. Inlet filter to block dirt particles and ensure longer life of the arrester 5. Regulator-mounted design for maximum safety at the gas source 6. Durable, industrial-grade build suitable for LPG and acetylene applications Applications 1. LPG / Acetylene welding 2. Cutting torch operations 3. Fabrication workshops 4. Industrial manufacturing units 5. Metalworking and repair shops 6. Gas-line safety systems for welding setups
