0790-0170 - Victor RK-STSL-X Torch Repair Kit for ST Series

Keep Your Victor Torch Burning Clean and Safe

Every welder knows that a leaky torch is not just an annoyance—it's a safety hazard and a quality killer. The Victor 0790-0170 Repair Kit RK-STSL-X is your go-to solution for bringing your trusty Victor straight torch back to life. If you are running an ST 900FC, ST 1000FC, or the heavy-duty ST 2600FC, you know these torches are built like tanks. However, even tanks need maintenance. The rubber O-rings and seals inside your torch eventually dry out, crack, or wear down from constant turning of the valves. When that happens, you might smell gas, feel a draft around the handle, or notice your flame wandering even after you've set it. That is your sign to grab this kit.

Don't risk a flashback or waste expensive gas fighting a worn-out torch. This kit contains everything you need to do a full internal reseal. It’s not just a bag of random O-rings; these are genuine Victor parts designed to handle the specific pressures and gases your torch uses. Swapping out the old seals for these new ones will make your oxygen and fuel knobs feel smooth and precise again, giving you that fine control you need for a perfect neutral flame. It’s a quick bench job that saves you the cost of buying a brand-new torch.

We know that in the shop, time is money. You don't want to spend half the morning trying to figure out why your preheat keeps changing. By rebuilding your torch with the RK-STSL-X kit, you eliminate the variables. You get a consistent flow, a tight seal, and the peace of mind that comes with using OEM parts. Whether you are cutting scrap, beveling plate, or doing structural demolition, your equipment needs to be as ready as you are. This repair kit is cheap insurance against downtime and accidents.

This kit is specifically for the "straight" style torches—the long ones used for floor cutting and machine work—not the combination torch handles. If your Victor torch has seen better days, don't toss it. Crack it open, clean it out, and install the 0790-0170 kit. You'll be surprised at how much better it cuts when the internals are fresh. Keep one in your toolbox so you're never stuck with a leaking torch in the middle of a job.
