► Flashback Arrestors

Flame Safety That Meets Code

Gas flashbacks are dangerous, unpredictable—and entirely preventable. Our Flashback Arrestors collection is built for trade crews who take gas safety seriously. Whether you’re running an oxy-acetylene kit in the field or running high-pressure lines in a workshop, these arrestors are your first and last line of defence.

Each unit is compliant with AS4603, providing thermal shutoff and non-return valves to protect both torch and regulator ends. We stock torch-mounted, regulator-mounted, and dual arrestor kits—compatible with standard BOC/CIG threads and suited for oxygen, acetylene, LPG, and other fuel gases.

Trusted by boilermakers, plumbers, HVAC techs, and metal fabricators, these are the same flame traps relied on in workshops, factories, and mobile welding units across the country. From Weldclass to Weldtronic, we only stock gear built to protect your crew and your equipment—because no job is worth a blowback.
