0739-0003 - Victor SR3 Regulator Seat Cartridge Assembly

Precision Engineering for Gas Control Systems

The Victor 0739-0003 Cartridge Assembly is a critical replacement component designed specifically for the SR 3 series of heavy-duty industrial regulators. In the realm of gas regulation, the seat assembly acts as the heart of the pressure control mechanism, modulating the flow of high-pressure gas from the cylinder into a manageable working pressure. Over time, the intense friction and pressure differentials inherent in oxy-fuel and inert gas applications can cause wear on the seating surface, leading to performance degradation. This genuine Victor part is manufactured to the exact tolerances required to restore your equipment to its original factory specifications.

Constructed from high-grade brass and utilizing advanced polymer seating materials, this cartridge assembly is engineered to withstand the rigors of industrial environments. The integrity of the seat is paramount; a compromised seat can lead to "creep," a condition where outlet pressure rises inadvertently when the downstream flow is stopped. By replacing the old assembly with the 0739-0003, technicians can effectively eliminate this safety hazard and ensure stable, reliable gas delivery. This component is compatible with a range of Victor's most popular heavy-duty models, including the SR 350, SR 360, and SR 700 series, making it an essential stock item for maintenance departments and repair facilities.

Installation of the cartridge assembly is a straightforward procedure for qualified personnel, designed to extend the lifecycle of expensive regulation hardware. Rather than discarding a regulator due to a worn internal component, the 0739-0003 allows for a cost-effective refurbishment that maintains the UL listing and safety standards of the device. Whether used in fabrication shops, shipyards, or construction sites, maintaining your Victor regulators with genuine OEM parts ensures consistent performance and protects downstream equipment from over-pressurization events.
