0740-0100 - Victor High Pressure Seat Assembly for SR 450/460 Regulators

Restore Your Regulator's Performance

Don't let a creeping regulator compromise your weld quality or shop safety. The Victor 0740-0100 Seat & Stem Assembly is the authentic repair part you need to fix your Victor heavy-duty regulators. If you own a Victor SR 450, SR 460, or SR 700 series regulator, this is the specific high-pressure seat designed to bring it back to life. Regulators are built to last, but the internal soft parts are wear items that eventually need replacement. Instead of scrapping a high-quality brass regulator, a simple rebuild with the correct seat assembly can make it perform like new again.

Why is this part important? The seat and stem assembly controls the flow of high-pressure gas from your cylinder. If you notice your delivery pressure gauge needle slowly climbing when you aren't cutting or welding, your seat is likely worn or damaged. This "creeping" pressure is a sign that gas is leaking past the seat. The Victor 0740-0100 replaces the worn sealing surface with a fresh, factory-spec component, ensuring a tight seal and stable pressure delivery.

Genuine Victor Quality: When it comes to gas equipment, fit and finish matter. This assembly is made by Victor for Victor equipment. It drops right into place during a standard overhaul, eliminating the guesswork associated with generic parts. The brass construction resists corrosion, and the specialized seat material is designed to withstand the high velocity of opening cylinder valves (though you should always open valves slowly!).

Whether you are a professional repair technician or a skilled fabricator maintaining your own gear, using the 0740-0100 Seat & Stem Assembly ensures your equipment remains reliable. Keep your oxy-fuel or inert gas setup running safely and efficiently by replacing worn internal components with original Victor parts. It’s the smart, economical way to maintain your industrial gas apparatus.
