0740-0119 - Victor SR 450/460 Regulator Seat and Stem Replacement Part

Stop the Creep and Weld Safely

If you've noticed your heavy-duty Victor regulator's gauge needle slowly climbing even when your torch is off, you're dealing with "pressure creep," and it's a sign that your internal seat has failed. The Victor 0740-0119 Seat & Stem Assembly is the exact part you need to fix this dangerous issue on your SR 450 or SR 460 regulator. A compromised seat doesn't just mess with your flame settings; it can lead to diaphragm damage or safety valve blowouts if left unchecked. This genuine replacement part brings your trusty regulator back to life, saving you the cost of buying a brand-new unit.

Designed for the workhorses of the industry—the heavy-duty regulators found in scrap yards, fabrication shops, and shipyards—this seat and stem assembly is built to handle the pressure. It swaps out the worn internal valve that controls gas flow, giving you back that crisp, responsive pressure adjustment you had when the gear was new. Don't risk your weld quality or your safety with generic knock-offs that might not seal correctly. Stick with genuine Victor parts to ensure your equipment handles the cylinder pressure safely and reliably.

Maintenance is part of the job, and keeping your gas equipment in top shape is non-negotiable for professional welders. Whether you are running oxygen, acetylene, or propane through your heavy-duty rig, this seat assembly is the heart of your pressure control. Installing this part is a straightforward fix for experienced equipment repairers, getting you back to cutting and welding with a stable, consistent flame. Keep your gear running as hard as you do with the right replacement parts.
