Victor Vanguard 0657-0035 Oxygen Flashback Arrestor for 100FC/315FC

Stay Safe with the Victor 0657-0035 Oxygen Flashback Arrestor

When you're under the hood or handling a torch, the last thing you want to worry about is a flashback. The Victor 0657-0035 Flashback Arrestor Assembly is your first line of defense against flame traveling back up your lines. Designed specifically for the popular Victor 100FC and 315FC torch handles, this little piece of brass packs a serious punch in the safety department. It’s not just an adapter; it’s a life-saver that screws right onto your torch handle.

This unit does double duty. First, it has a built-in reverse flow check valve. That means if your pressures get out of whack or a tip gets clogged, the oxygen won't backfeed into your fuel line (or vice versa if you have the set), preventing that dangerous mix that leads to pops and bangs. Second, and most importantly, it has a flashback arrestor inside. If a flame does manage to pop back into the torch, the sintered metal filter inside this assembly snuffs it out instantly, stopping it dead before it can reach your hoses or regulators.

The 0657-0035 comes with standard 9/16"-18 Right Hand threads, which means it's designed for your Oxygen line (remember: Righty-Tighty for Oxygen). It fits perfectly on Vanguard series handles without making the torch feel front-heavy or awkward to hold. Unlike some bulky aftermarket arrestors that hang off your regulators, these torch-mount units stop the trouble right at the source—in your hand—giving you maximum protection where it counts.

Don't take chances with old or missing safety gear. If your torch handle's built-in arrestors are worn out or if you are rebuilding a setup, this is the factory-correct part to get you back to burning metal safely. It’s tough, reliable, and built by Victor, so you know it can handle the daily grind of the shop or the field.
