0740-0131 - Victor Regulator Seat and Stem Replacement Kit

Precision Gas Control Restoration

The Victor 0740-0131 Seat & Stem Assembly is a critical replacement component designed to restore the functionality and safety of Victor heavy-duty gas regulators. In the hierarchy of regulator components, the seat assembly acts as the primary valve mechanism, modulating the flow of high-pressure gas from the cylinder into the low-pressure chamber. Over time, the elastomeric seat material can degrade due to mechanical wear, debris, or age, leading to a failure mode known as "creep," where delivery pressure rises uncommanded when the downstream flow is stopped.

This genuine Victor assembly is engineered to exact OEM specifications, ensuring a perfect seal and precise flow control. It is specifically manufactured for compatibility with the widely used SR 450 and SR 460 series regulators, which are staples in industrial environments. The assembly features a precision-machined brass stem and a high-durability seat material capable of withstanding the rigorous demands of high-pressure oxygen, acetylene, and inert gas service. Utilizing genuine OEM parts for regulator repair is essential for maintaining the equipment's UL listing and ensuring operator safety.

Technicians and safety officers recognize that a compromising regulator seat is a significant hazard. By replacing the worn assembly with the 0740-0131, you eliminate pressure fluctuations and ensure that the regulator maintains a steady, set pressure, which is vital for process consistency in welding, cutting, and heating applications. This component is the definitive solution for extending the service life of your premium gas control equipment.
