Play it Safe Designed to instal easily between regulators and hoses, flashback arrestors suppress dangerous flames before reaching the fuel source, keeping you safe. Features internal cheque valves, which are designed to prevent the reverse flow of gas, one of the major causes of flashback. Use a quick-connect between the flashback arrestor and hose so you can instantly connect or disconnect your torch without turning off the gas supply. Durable solid brass connectors are colour-coded and feature reverse flow cheque valves designed to prevent accidental gas mixing. An automatic shut-off valve ensures that the gas flow is completely shut off when disconnected.
