0740-0115 - Victor Regulator Seat Assembly 0740-0115 for SR 450/460

Restore Precision Control with Genuine Victor Components

The Victor 0740-0115 Seat & Stem Assembly is a critical replacement component designed specifically for heavy-duty Victor gas regulators, including the renowned SR 450, SR 460, and SR 700 series. In the realm of industrial gas control, the seat assembly acts as the heart of the regulator, modulating the flow of high-pressure gas from the cylinder to the delivery side. Over time, the constant mechanical stress of opening and closing, combined with the high-velocity flow of gas, can wear down the seating surface. This wear often manifests as 'creep,' a condition where the delivery pressure inadvertently rises when the torch or downstream valve is closed. Replacing the seat assembly with this genuine OEM part is the definitive solution to restoring safe and accurate performance.

Manufactured to Victor's exacting engineering standards, this assembly ensures a perfect seal against the regulator nozzle. The materials used are selected for their durability and compatibility with various industrial gases, including oxygen, acetylene, and inert shielding gases. In high-pressure oxygen applications, the quality of the seat material is paramount to prevent adiabatic compression ignition; generic substitutes may not meet the rigorous safety testing standards that Victor Equipment applies to their OEM parts. By choosing the 0740-0115, maintenance personnel ensure that the regulator maintains its pressure stability, flow characteristics, and safety margins.

This component is essential for MRO (Maintenance, Repair, and Operations) professionals tasked with certifying and repairing gas equipment. It allows for the extension of the service life of expensive heavy-duty regulators, providing a cost-effective alternative to full unit replacement. Whether used in a fabrication shop, a laboratory, or a heavy construction site, a properly maintained regulator is key to process consistency and operator safety. Ensure your equipment fleet remains compliant and operational by utilizing only authentic Victor replacement parts for all regulator overhauls.
