0740-0064 - Victor Regulator Replacement Seat Assembly 0740-0064

Keep Your Victor Regulator Running Like New

There is nothing more frustrating than a regulator that won't hold pressure. You set your torch to the perfect flame, start welding or cutting, and suddenly your flame changes because the delivery pressure is creeping up. This phenomenon, known as "creep," is a tell-tale sign that the internal seat in your regulator is worn out. Instead of tossing your expensive heavy-duty Victor regulator in the trash and spending hundreds on a replacement, you can often fix the issue for a fraction of the cost with the Victor 0740-0064 Seat Assembly.

This is the genuine article—not a cheap knock-off. It is the exact replacement part used in legendary Victor regulators like the SR 450 and SR 460 series. These regulators are built to last a lifetime, but the soft parts inside, like this seat assembly, are consumables. Every time you crack open a cylinder valve, high-pressure gas slams into this seat. Over years of service, it takes a beating. Replacing it is a standard maintenance procedure that brings your gear back to factory performance standards.

Why does the seat matter? The seat assembly is the gatekeeper of your gas flow. It opens and closes thousands of times to maintain the pressure you set. If it gets a microscopic scratch from debris or simply wears down, gas leaks past it even when you aren't using the torch. This causes the pressure on your gauge to slowly climb, which can be dangerous and annoying. Swapping out the old seat for a fresh 0740-0064 stops this drift instantly.

For professional welders and fabricators, maintaining your own equipment is part of the trade. Keeping a spare seat assembly in your toolbox ensures that a blown regulator doesn't shut down your job site. Whether you are running oxygen, acetylene, or shielding gas, if your Victor regulator uses this part number, this is the fix you need. Ensure your safety and the quality of your cuts and welds by keeping your gas delivery system in top shape with genuine Victor parts.
