Flashback arrestors stop a flame from travelling back through the hose into the regulator and gas cylinder. They are a basic safety device for oxy-acetylene and oxy-LPG cutting and welding outfits. This collection includes arrestors from Harris, Koike, Victor, Procut, Supercut, Morweld and Megatools.
How to choose a flashback arrestor
- Gas type: use an oxygen arrestor on the oxygen line and an acetylene or LPG arrestor on the fuel gas line. They are not interchangeable.
- Regulator or torch end: regulator-mounted arrestors such as the Megatools FO288R and FA288R fit at the cylinder. Torch-mounted ones like the FO188T and FA188T fit at the torch handle. Many users fit both.
- Thread direction: oxygen fittings use right-hand threads and fuel gas fittings use left-hand threads, so buy them as a pair.
Use with
Fit arrestors to your oxygen regulator and acetylene regulator, or see complete welding and cutting outfits.
All products from KHM Megatools are genuine.
