0790-0166 - Victor RK-ESS4-F Repair Kit for ESS4 and G350 Fuel Gas Regulators

Get Your Regulator Back in the Game

There is nothing more frustrating than gearing up for a cut or a weld only to find your acetylene regulator is creeping or leaking. Not only is it a hassle, but it is also a significant safety risk. The Victor 0790-0166 Repair Kit (RK-ESS4-F) is your solution to bringing your trusted Victor ESS4 or G350 fuel gas regulator back to life. Instead of shelling out the cash for a brand-new regulator, this kit gives you everything you need to rebuild the internals of your existing unit, making it work like new again.

Victor's Edge Series (ESS4) and G-Series (G350) are built tough, but even the best gear needs maintenance eventually. The soft parts inside—like the seat and the diaphragm—take the brunt of the work every time you open and close the cylinder valve or adjust your pressure. Over time, these parts wear out, leading to unstable flames or gas waste. This kit includes a new seat assembly, diaphragm, and all the seals you need to swap out the worn components. It is the exact same hardware Victor puts in the regulator at the factory, so you know it fits perfectly and holds up to the job.

Repairing your regulator is a smart way to save money and keep your shop running smoothly. If you notice your delivery pressure gauge rising when your torch is off, or if you can't get a steady flow, it's time for a rebuild. With the RK-ESS4-F kit, you can fix the problem at the source. Please remember, regulator repair involves high-pressure gas equipment; if you aren't trained in regulator repair, it is best to have a professional install the kit for you. Keep your flame steady and your shop safe with genuine Victor parts.
