5233-4521 - Victor Regulator Seat Assembly Replacement

Restore Your Regulator's Performance

Is your trusty Victor regulator acting up? If you are noticing your delivery pressure gauge creeping up when you aren't using the torch, or if you can't seem to get a stable flame, the problem is likely inside the regulator's heart: the seat assembly. The Victor 5233-4521 Seat Block Assembly is the genuine replacement part you need to bring your heavy-duty Victor regulators back to life. Designed for the workhorses of the industry—the SR 450, SR 460, and SR 700 series—this part is the key to fixing leaks and pressure issues without having to buy a brand-new regulator.

Regulators are tough, but the internal seat takes a beating every time you crack open a cylinder valve. High-pressure gas slams into the seat, and over years of service, this can cause wear or indentations that prevent a perfect seal. When that happens, gas sneaks past the valve, causing dangerous pressure buildup. By swapping out the old block for this fresh, factory-original 5233-4521 assembly, you ensure a tight, reliable seal that holds pressure exactly where you set it. It’s a smart, cost-effective repair that extends the life of your equipment and keeps your shop safe.

Don't settle for generic aftermarket parts when it comes to gas safety. This Victor seat block is machined to exact specifications, ensuring it drops right into place during your rebuild. Whether you are a professional repair technician or a welder who takes pride in maintaining their own gear, this assembly makes the rebuild process straightforward. Keep your cuts clean, your welds strong, and your shop safe by maintaining your gas equipment with the best parts available. A rebuilt regulator with a new seat block performs just like the day you bought it.
