22305 - ESAB R-522 Regulator Replacement Diaphragm

Restore Your R-522 Regulator to Peak Performance

If your trusty R-522 regulator has started acting up, don't rush to replace the whole unit just yet. The ESAB 22305 Diaphragm is the exact part you need to breathe new life into your equipment. We know that the R-522 is a legend in the industry—tough, reliable, and built to last. However, even the toughest gear needs maintenance. The diaphragm is the moving part that does the heavy lifting every time you adjust your pressure. After thousands of cycles and years of service, it can lose its elasticity, stiffen, or develop small cracks. This often results in "creeping" pressure on your gauges or erratic flame behavior at the torch.

Swapping out a worn diaphragm with this genuine ESAB replacement is a smart investment. It fixes the common issues that make a regulator unsafe or frustrating to use. When a diaphragm fails, you might notice a humming sound during operation or find that you can't hold a steady pressure setting. Ignoring these signs can be dangerous, especially when dealing with oxy-fuel processes. By installing the 22305, you are ensuring that your gas flow remains consistent, which directly translates to better cut quality and cleaner welds. You don't have to fight your equipment; you just need to give it the right parts.

This diaphragm is designed for straightforward installation by qualified repair technicians. It fits perfectly into the R-522 housing without the need for modification or guesswork. Unlike cheap aftermarket knock-offs that might be too thick or too thin, this part has the correct sensitivity to react instantly to your adjustments. Keep your shop running smoothly and your safety standards high by maintaining your regulators with authentic ESAB components. Whether you are running acetylene, propane, or oxygen, a healthy diaphragm is the key to a safe and controlled flame.
