0739-0033RP - Victor SR4 Regulator Seat Cartridge Repair Assembly

Genuine Victor Replacement for SR4 Regulators

The Victor 0739-0033RP Cartridge Assembly is a critical replacement component designed specifically for the SR4 Series of heavy-duty regulators. In industrial gas control systems, the regulator seat and stem mechanism—housed within this cartridge—are subject to wear over time due to high-pressure gas flow and mechanical cycling. When these components degrade, regulators may exhibit "creep" (rising delivery pressure when the torch is closed) or internal leaks, compromising safety and precision.

This OEM cartridge assembly simplifies the rebuilding process. Rather than handling minute individual springs and seats, the cartridge provides a pre-assembled unit that fits perfectly into the regulator body. This ensures that factory specifications for flow and pressure control are met after the repair. Using genuine Victor parts is essential for maintaining the safety certifications and operational integrity of your gas equipment.

Ideal for maintenance departments and certified repair technicians, this part extends the service life of your SR4 regulators, offering a cost-effective alternative to purchasing new equipment. Whether used in heavy fabrication, pipeline work, or manifold systems, ensuring your regulators are functioning correctly is paramount for process consistency.
