0740-0135 - Victor SR 450/460 High Pressure Seat and Stem Repair Kit

Restore Your Regulator's Performance and Safety

Don't let a worn-out regulator compromise your safety or your weld quality. The Victor 0740-0135 High Pressure Seat and Stem Assembly is the genuine replacement part you need to bring your heavy-duty Victor regulators back to life. If you use the robust SR 450, SR 460, or SR 700 series regulators, you know they are built to last a lifetime—but only if maintained properly. The most common failure point in any regulator is the high-pressure seat, which takes the brunt of the force every time you crack open a cylinder valve.

Signs You Need This Part: The classic symptom of a failed seat is "gauge creep." This happens when you stop cutting or welding, but you watch your delivery pressure gauge needle slowly climb higher and higher. This is a dangerous condition that indicates high-pressure gas is leaking past the internal seal. Not only does this waste gas, but it can also lead to blown diaphragms, damaged hoses, or hazardous pressure spikes at your torch. Instead of spending hundreds of dollars on a brand-new regulator, you can fix the issue for a fraction of the cost with this simple replacement assembly.

Why Choose Genuine Victor? When dealing with high-pressure oxygen or fuel gases, you cannot afford to take chances with aftermarket knock-offs. The 0740-0135 is the exact OEM part used in the factory assembly of your regulator. It guarantees a perfect fit and a reliable seal that will hold up to the rigors of daily shop use. Whether you are working in a fabrication shop, a scrap yard, or on a pipeline, keeping your equipment in top shape is part of the job. This seat and stem assembly is easy to install for those experienced in equipment repair and is the best insurance policy for your heavy-duty gas gear.

Keep a spare 0740-0135 in your maintenance kit so you are never down for long. By replacing the seat and stem at the first sign of trouble, you ensure consistent flame characteristics, smooth flow rates, and a safe working environment for everyone in the shop.
