Bulgin GRS50 Gas Flashback Arrestor Brass 1 1/2" (40mm) BSP Female

The Bulgin GRS50 Gas Flashback Arrestor is an industrial gas safety device designed for the protection of ring lines, tapping points, and points of use. This unit provides reliable pressure-related safety functionality but is not flashback resistant, making it suitable for applications where flame arresting is not required. Engineered for stable operation with position-independent low cracking pressure, it supports a wide range of fuel, oxidising, and inert gases in industrial gas distribution systems.
