Flashback arrestors are a must for all torch users! Built with in-line check-valves, arrestors prevent a hose fire from reaching the regulators or tank. They are strongly recommended for all torches—especially casting torches. This dual duty arrestor also cuts off gas flow when the pressure drops to 0.5psi, an added safety feature for your business. Sold in pairs, the arrestors in this set feature 'B' fittings and attach at the regulator end of your set-up.
Fitting sytle: 'B' fitting
Flashback arrestors are required in several cities and states; please check your local regulations for compliance details.
