0740-0151 - Victor 0740-0151 High Pressure Seat Assembly for SR 450/460 Regulators

Keep Your Victor Regulator Running Like New

Is your heavy-duty Victor regulator acting up? If you notice the pressure gauge creeping up after you've stopped cutting, or if the regulator makes a strange humming or vibration noise during use, it's likely time to replace the seat assembly. The Victor 0740-0151 Seat & Stem Assembly is the genuine replacement part you need to fix these common issues and get back to work safely. A leaking or creeping regulator isn't just an annoyance—it's a safety hazard that can blow hoses or damage your torch. Swapping out the old, worn-out seat for this brand-new OEM part is the best way to protect your gear and yourself.

Designed for the workhorses of the welding industry, this seat assembly fits the legendary Victor SR 450, SR 460, and SR 700 series regulators. These are the big, heavy-brass regulators found on rig trucks, in shipyards, and in fabrication shops everywhere. Because these regulators handle high pressures and high flow rates, the internal seat takes a beating over time. The 0740-0151 is built to withstand that punishment, using durable materials that seal tight and resist wear. Don't trust your safety to cheap knock-offs; this is the exact part Victor put in the regulator when it was built.

Repairing your regulator is often much cheaper than buying a new one, especially when you are dealing with high-end equipment like the SR 450 series. By installing a new seat and stem assembly, you are essentially giving your regulator a new lease on life. The repair restores that crisp, steady flame adjustment you expect from Victor equipment. It eliminates the frustration of constantly readjusting your pressure knob and ensures that when you set your PSI, it stays there.

Why Choose Genuine Victor Parts?

When you are dealing with compressed gases like Oxygen and Acetylene, fit and finish matter. Genuine Victor parts are machined to tight tolerances to ensure they seat perfectly inside the regulator body. This assembly comes ready to install, combining the stem and the sealing material into one unit, so you don't have to fiddle with small components. Keep a spare in your toolbox so a blown seat never shuts down your job site.
