19A23 - ESAB R52 Regulator Replacement Diaphragm

Fix Your Regulator and Get Back to Work

Is your R52 regulator acting up? If you are noticing fluctuating pressures, gas creep (where the pressure rises when you aren't welding), or hearing leaks from the bonnet, it might be time to replace the diaphragm. The ESAB 19A23 Diaphragm is the direct replacement part you need to fix these common issues and get your gear running like new again.

Regulators take a beating in the shop and on the truck. The internal diaphragm is the moving part that does all the work, flexing thousands of times to keep your gas flow steady. Eventually, it wears out. Don't risk a bad weld or a safety hazard with a faulty regulator. Swapping out the old diaphragm with this genuine ESAB replacement is a cost-effective way to save your regulator instead of buying a whole new unit.

This part is designed to fit perfectly inside R52 series models, so you don't have to worry about leaks or poor fitment. It’s built tough to handle the rigors of daily welding and cutting. Whether you are running oxygen, acetylene, or shielding gas mixes, a fresh diaphragm ensures your flowmeter or gauge reads true and your torch gets the steady gas stream it needs for a clean bead or cut.

Why Replace Your Diaphragm?

• Stop Leaks: Fixes internal leaks that waste gas and cause safety hazards.
• Steady Flow: Eliminates pressure spikes that can blow out your puddle.
• Save Money: Repairing your high-quality regulator is cheaper than replacing it.
