0740-0008 - Victor SR Series Regulator High Pressure Seat Assembly

Keep Your Victor Regulator Running Like New

If you are running a heavy-duty Victor regulator like the SR 450 or SR 460, you know these pieces of equipment are built like tanks. However, even the toughest gear needs maintenance eventually. If you have noticed that your working pressure gauge starts to slowly climb after you have finished a cut or stopped welding, your regulator is suffering from "creep." This is a classic sign that your internal seat is worn out or damaged. The Victor 0740-0008 Seat & Stem Assembly is the exact part you need to fix this problem and get your regulator back to safe, reliable operation.

Why repair instead of replace? A high-quality Victor regulator is an investment. Buying a cheap knock-off replacement often leads to frustration with inconsistent flow rates and poor durability. By swapping out the seat and stem with this genuine Victor part, you are essentially giving your trusty regulator a new heart. This assembly controls the massive pressure coming out of your tank, stepping it down to the safe levels you need for your torch. It is the most hardworking part of the device, opening and closing thousands of times.

The 0740-0008 is designed to fit the big boys of the Victor lineup—the SR 450, 460, and 700 series. These are the regulators found in shipyards, heavy fabrication shops, and on the trucks of serious rig welders. Don't trust your safety to generic parts that might not seal correctly. A leaking seat can be dangerous, leading to blown diaphragms or popped safety relief valves. This OEM kit ensures a perfect seal every time.

Installation is straightforward for those experienced with regulator repair. Just remember the golden rule of oxygen equipment: keep everything absolutely clean and free of oil or grease. With this new seat and stem, you can stop tapping your gauge to check the pressure and get back to focusing on your bead. Extend the life of your equipment and maintain the precision flow control that Victor is famous for.
