0731-0062 - Victor 0731-0062 Stainless Steel Diaphragm for SR 450/460 Series Regulators

Precision Replacement for Heavy-Duty Regulation

The Victor 0731-0062 Diaphragm is a critical replacement component designed to restore the functionality and safety of your heavy-duty gas regulators. Specifically engineered for the renowned Victor SR 450, SR 460, and SR 700 series, this diaphragm is the heart of the pressure control mechanism. Unlike standard neoprene or rubber diaphragms, this unit is constructed from high-quality stainless steel. This material choice is deliberate, offering exceptional resistance to corrosion, chemical attack, and temperature extremes, making it suitable for a wide range of industrial gases and demanding environments.

In the realm of gas regulation, the diaphragm acts as the sensing element that balances the spring force against the outlet pressure. Over time, metal diaphragms can suffer from fatigue or deformation, leading to issues such as pressure creep (where outlet pressure rises when flow stops) or erratic flow delivery. Replacing a compromised diaphragm with a genuine Victor 0731-0062 ensures that your equipment returns to factory specifications. The stainless steel construction also makes this diaphragm ideal for applications requiring higher purity, as it eliminates the risk of off-gassing associated with some elastomeric materials.

Maintenance of gas equipment is paramount for safety and efficiency. A failing regulator can pose significant risks, including equipment damage and personnel hazards. By utilizing genuine OEM parts like the 0731-0062, you ensure proper fitment and sealing integrity. This assembly is manufactured to tight tolerances, ensuring it responds accurately to pressure changes, providing the stable flow required for precision cutting, welding, or laboratory applications. Whether you are rebuilding a vintage SR 450 or maintaining a fleet of SR 700s, this stainless steel diaphragm is the professional's choice for reliability.

Key Technical Benefits:

• Material Integrity: Stainless steel offers superior fatigue life and chemical compatibility compared to rubber alternatives.


• Precise Control: Engineered stiffness ensures accurate response to pressure fluctuations, maintaining steady delivery pressure.


• OEM Compatibility: Guaranteed fit for Victor's heavy-duty regulator lines, eliminating guesswork during repair.
