The ESAB Victor 0740-0131 is a genuine OEM heavy-duty seat and stem assembly designed as the primary high-pressure sealing component for Victor SR 450 and SR 460 series industrial gas regulators. It functions as the internal valve that regulates the flow of high-pressure gas from the cylinder into the low-pressure chamber to maintain set delivery pressure and prevent regulator creep. The assembly consists of a precision-machined stem and a high-density PTFE encapsulated seat designed to seal against the regulator nozzle.
Features
High-density PTFE encapsulated seat for high-pressure sealing integrity
Precision-machined stem for exact alignment with the regulator nozzle
OEM replacement part ensures compliance with original material specifications
Drop-in replacement design for standard regulator maintenance
