0740-0104 - Victor Regulator High Pressure Seat and Stem Repair Kit

Stop the Creep and Fix Your Regulator

If your Victor regulator is acting up, specifically if you notice the pressure gauge climbing even when you aren't cutting, you likely have a worn-out seat. The Victor 0740-0104 Seat & Stem Assembly is exactly what you need to fix that problem and get back to work safely. In the welding and cutting world, your gear takes a beating, and the internal components of your regulator are under constant stress from high-pressure gas. Eventually, the seat that controls that pressure wears out, and that's when you start seeing performance issues.

This isn't just some generic knock-off part; it's the real deal from Victor. When you are dealing with high-pressure oxygen or fuel gases, you don't want to take chances with parts that "might" fit. This assembly drops right into compatible Victor regulators, replacing the old, worn-out stem and seat. It seals up tight to stop leaks and ensures that when you set your pressure, it stays there. No more constantly adjusting the knob or worrying about the pressure spiking while you are trying to focus on your weld or cut.

Replacing the seat and stem is a standard maintenance task that can save you the cost of buying a brand-new regulator. A bad seat causes "creep," where gas sneaks past the valve, pressurizing the hose when it shouldn't. This can blow out diaphragms or even cause hoses to rupture if left unchecked. By swapping in a fresh 0740-0104 assembly, you are essentially giving your regulator a new lease on life. It’s a small part that does a huge job, keeping your gas flow steady and your shop safe.

Whether you are running a busy fabrication shop or just maintaining your own rig, keeping a spare seat and stem assembly on hand is a smart move. It allows for quick repairs so you aren't stuck waiting on parts when you have a deadline to meet. This assembly is built tough, with durable brass construction and a high-quality seat material that resists wear, giving you reliable performance for the long haul. Don't let a creeping regulator slow you down—fix it right with genuine Victor parts.
