Description
Overview:
This fuel-gas flashback arrestor is a compact safety device for oxy-fuel equipment used in welding, cutting, brazing and heating. Built around a durable brass body with a 3/8" (9.5 mm) BSP left‐hand nut, it installs inline to protect torches, hoses, regulators and cylinders from dangerous reverse flame travel. A thermally activated cut-off mechanism automatically stops gas flow during a flashback and requires no manual resetting, helping maintain protection with minimal intervention. Compatible with propane and other common fuel gases, it is suitable for workshop and site use across fabrication, maintenance and construction settings. The clear flow-direction marking supports correct installation. MPN 200 195. Sold individually, so you can replace a single arrestor or equip specific hoses or tools as needed.
