A consistent flame or arc starts with consistent gas flow. If your regulator is acting up—letting pressure climb when you aren't cutting, or fluctuating while you weld—the diaphragm is often the culprit. The ESAB 998380 Diaphragm Assembly is the genuine repair part you need to fix these issues and get back to work. Don't struggle with an unstable arc or a wandering flame; swapping out a worn diaphragm is a standard maintenance procedure that can save you the cost of buying a brand-new regulator.
This assembly is built tough, just like the ESAB equipment it fits. It includes the diaphragm material and the center assembly plate (where applicable), ready to drop into your regulator's bonnet. Using genuine parts means you don't have to worry about whether the bolt holes line up or if the material is rated for the gas you are using. It is designed to handle the rigors of daily shop use, ensuring that when you set your PSI, it stays there.
Whether you are repairing an oxy-fuel cutting rig or a shielding gas setup for MIG/TIG, trusting genuine ESAB parts protects your investment and your safety. A blown diaphragm isn't just an annoyance; it's a safety hazard. Keep your shop running smoothly and safely by replacing worn internal components with the 998380 Diaphragm Assembly.
