OVERVIEW

Fix Your Regulator with the Genuine Victor 0730-0055 Assembly

Don't let a leaking or creeping regulator slow down your fabrication projects. The Victor 0730-0055 Diaphragm/Relief Assembly is the exact OEM part you need to rebuild your trusted Victor SR 450, SR 460, or SR 700 series regulator. If you've noticed your delivery pressure gauge climbing when your torch is off—a phenomenon known as "creep"—or if you hear a humming noise during operation, it's likely time to replace the diaphragm. This assembly provides a cost-effective solution to extend the life of your premium equipment without the expense of buying a brand-new regulator.

This kit features a high-quality neoprene diaphragm pre-assembled with the metal center plate and relief valve mechanism. The inclusion of the relief valve is crucial; it acts as your last line of defense against high-pressure blowouts, venting gas safely if the seat fails. Because it is a genuine Victor product, you don't have to worry about fitment issues or guessing if the relief setting is correct. It drops right into place, restoring the sensitive balance required for smooth flame adjustment and consistent gas flow.

Repairing your own equipment can be a smart way to save money and minimize downtime, provided you use the right parts. The 0730-0055 is built to withstand the rigors of daily shop use. The neoprene material remains flexible even in varying temperatures, ensuring a tight seal and responsive pressure control. Whether you are running oxygen, acetylene, or inert gases, keeping your regulator's internals in top shape is essential for weld quality. A fluctuating arc or unstable flame caused by a bad regulator can ruin your workpiece. Swap out that old, stiff diaphragm with this fresh assembly and get back to welding with confidence.

Why Choose OEM?

While generic repair kits exist, they often lack the precise engineering of the original manufacturer. Victor's diaphragms are tested for specific elasticity and strength. Using the 0730-0055 ensures that your pressure adjustments remain linear and predictable. Keep a spare in your toolbox so you're never caught off guard by a regulator failure in the middle of a critical job.

FAQ

This diaphragm assembly is designed for Victor SR 450, SR 460, and SR 700 series heavy-duty regulators.

Common symptoms include pressure creep (pressure rising on the gauge when the torch is closed), gas leaking from the regulator bonnet, or a humming/vibrating sound during gas flow.

Yes, the 0730-0055 is a complete assembly that includes the diaphragm and the integrated relief valve mechanism.

Yes, this is an authentic Victor Technologies (ESAB) OEM replacement part.

Yes, provided your regulator is one of the compatible series (SR 450/460/700). Always ensure all parts are kept free of oil and grease when working with oxygen equipment.

The '30#' typically refers to a specific pressure rating or relief setting associated with the assembly, often indicating a 30 PSIG relief or range, though it is specific to the regulator's design parameters.

Replacing a diaphragm requires disassembling the regulator bonnet. While straightforward, it should be performed by a qualified technician or someone experienced with gas equipment repair to ensure safety and proper torque specifications.

The relief valve is a safety device. Over time, springs can weaken or seals can degrade. Replacing the entire assembly ensures that the safety mechanism will function correctly if an over-pressure event occurs.
