0730-0066 - Victor High Pressure Diaphragm Replacement Kit

Restore Your Regulator's Performance

Is your Victor regulator letting you down? If you are experiencing inconsistent gas flow or noticing that your pressure gauge creeps up when you aren't cutting or welding, it might be time to replace the diaphragm. The Victor 0730-0066 HP Diaphragm Assembly is the genuine replacement part you need to get your high-pressure regulator back in top fighting shape. Don't risk your safety or the quality of your welds with aftermarket knock-offs; stick with the brand that built the equipment. This assembly is designed specifically for the high-pressure side of your regulator, handling the immense force of cylinder gases with ease.

We know that in the field, downtime is money. A failing regulator can halt production, ruin cuts, and create safety hazards. Instead of scrapping a high-quality brass regulator because of a worn internal part, you can rebuild it. This kit includes the complete diaphragm assembly, ready to drop into your compatible Victor housing. It is built to the exact specifications required to handle high-pressure oxygen, acetylene, or inert gases, ensuring that your flame stays neutral and your shield gas stays constant. The assembly is robust, designed to flex thousands of times without cracking or losing its seal.

Installing the 0730-0066 is a straightforward process for those experienced in equipment repair. By replacing the old, fatigued diaphragm with this fresh OEM part, you eliminate leaks and pressure spikes. This is particularly important for heavy-duty applications where precision is key. Whether you are running a heavy-duty SR 450 on a manifold system or a portable outfit in the back of a truck, maintaining the internal components of your regulator is part of being a professional. This part ensures that when you dial in 50 PSI, you get 50 PSI—no more, no less.

Keep your gear running as long as you do. Victor gas equipment is famous for lasting decades, but only if you maintain it with the right parts. The 0730-0066 High Pressure Diaphragm Assembly is an investment in the longevity of your tools. It’s the smart choice for welders, fabricators, and shop owners who value reliability and safety above all else. Don't let a $50 part turn into a $300 replacement regulator; fix it right with genuine Victor parts.
