0731-0004 - Victor 0731-0004 Replacement Regulator Diaphragm

Fix Your Regulator with the Victor 0731-0004 Diaphragm

If your Victor regulator isn't holding pressure like it used to, or if you notice the needle creeping up when you aren't cutting, it might be time to check the diaphragm. The Victor 0731-0004 is the factory-original replacement diaphragm you need to get your gear back in top shape. The diaphragm is the heart of your regulator—it flexes back and forth thousands of times to keep your gas pressure steady. Eventually, that rubber or composite material gets tired, stiff, or even develops small tears, which can lead to inconsistent flames and wasted gas.

Don't risk your welds or your safety with a faulty regulator. A bad diaphragm can cause dangerous pressure spikes or leaks that make it impossible to set a neutral flame. By swapping in this genuine Victor 0731-0004 replacement, you are ensuring that your regulator works exactly how it was designed to. It fits perfectly, seals tight, and reacts smoothly to your pressure adjustments. This isn't a cheap knock-off; it's the real deal from Victor, meaning it's built to handle the daily abuse of a welding shop or job site.

Keeping your oxy-fuel outfit in good condition saves you money in the long run. Instead of buying a whole new regulator, a simple rebuild with the right parts can extend the life of your tools for years. This diaphragm is designed for specific Victor models, so check your parts diagram to confirm the fit. Once installed, you'll notice the difference immediately—smooth pressure control and a gauge that stays exactly where you set it. Get your torch running right and get back to work with confidence.

Safety First: Gas regulators are high-pressure devices. If you aren't comfortable taking one apart, have a pro do it for you. Always leak test your gear after any repair.
