If your Victor heavy-duty regulator is exhibiting signs of "creep"—where the delivery pressure slowly rises when the torch valves are closed—it is likely time to replace the seat assembly. The Victor 0740-0118 Seat & Stem Assembly is the factory-correct replacement part for the legendary SR 450, SR 460, and SR 700 series regulators. The seat and stem are the most critical mechanical components inside your regulator, responsible for holding back cylinder pressure that can exceed 2,000 PSI. A compromised seat not only affects your flame characteristics but can also create safety hazards by allowing high-pressure gas to bypass the regulation diaphragm.
This assembly features a precision-molded seating material bonded to a durable stem, designed to create a perfect seal against the nozzle. Victor's engineering ensures that this part can withstand the mechanical stresses of opening and closing while maintaining a leak-tight seal. Whether you are working with oxygen, acetylene, or inert gases, using the correct seat assembly is vital. The 0740-0118 is built to handle the rigorous demands of heavy fabrication, shipyards, and structural work where Victor regulators are the standard.
Installation should always be performed by a qualified technician or in a clean environment to prevent oil or debris from entering the regulator, which is especially critical for oxygen service. Once installed, this assembly restores the responsive pressure control you expect from Victor equipment, providing a stable flame and consistent flow rates. Don't let a worn seat compromise your weld quality or safety; refurbish your trusted regulator with this genuine Victor component.
