OVERVIEW

Restore Your Regulator's Performance

Is your heavy-duty Victor regulator letting pressure creep up when you aren't cutting? That's a classic sign of a worn-out high-pressure seat. The Victor 0740-0103 HP Seat & Stem Assembly is the exact part you need to fix that issue and get your SR 450 or SR 460 regulator back to working like new. Don't risk your safety or your weld quality with a regulator that won't hold a steady pressure.

This isn't just a generic spare; it's the genuine article from Victor. When you're dealing with high-pressure oxygen or fuel gases, you want parts that fit perfectly and seal tight every time. This assembly drops right into compatible heavy-duty regulators, replacing the old, worn-out seat that causes leaks and pressure spikes. It's a smart, cost-effective repair that saves you from having to buy a brand-new regulator.

Why replace the seat?
A damaged seat allows high-pressure gas to sneak past the valve even when it should be closed or regulating. This "creep" can blow out your low-pressure gauge or diaphragm and create dangerous situations in the shop. Swapping in a fresh 0740-0103 assembly stops the creep, locks in your pressure settings, and keeps your flame steady. It's an essential maintenance item for any shop running Victor heavy-duty gear.

FAQ

This seat and stem assembly is designed for Victor heavy-duty regulators, primarily the SR 450, SR 460, and SR 700 series.

The most common symptom is 'creep,' where the delivery pressure gauge reading slowly rises after the torch valves are closed. This indicates the seat is not sealing against the nozzle properly.

Yes, this is a genuine Victor Technologies OEM replacement part, ensuring proper fit and material safety.

Regulator repair involves high-pressure gases and critical safety components. It is highly recommended that installation be performed by a qualified gas apparatus repair technician.

No, this SKU typically includes the Seat & Stem Assembly itself. Other internal components like friction dampers or springs are usually sold separately or reused if in good condition.

Creeping is usually caused by a damaged or dirty high-pressure seat. Debris from the cylinder or normal wear can prevent the seat from closing fully, allowing high-pressure gas to leak into the low-pressure chamber.

This is an individual component (the seat and stem). A full repair kit would typically include this part along with diaphragms, gaskets, and slip rings. If only the seat is damaged, this part alone may suffice.

There is no set time interval; it should be replaced whenever the regulator shows signs of performance issues like creeping or inability to hold pressure, or during scheduled overhauls.
