OVERVIEW

Restore Precision to Your Oxygen Supply

A consistent flame starts with a consistent flow. If your oxygen regulator is showing signs of age—like fluctuating pressures or a needle that creeps up when you stop cutting—it might be time to replace the diaphragm. The ESAB 999827 Diaphragm Assembly is the heart of your regulator, responsible for breathing life into your torch by reacting instantly to changes in demand. When this part wears out, your flame control suffers, leading to messy cuts and frustrating adjustments.

Don't compromise on safety when it comes to oxygen equipment. This genuine ESAB replacement part is engineered specifically for oxygen service, meaning it is manufactured free of oils and from materials that won't react dangerously with high-pressure oxygen. It provides the peace of mind that comes with using original equipment manufacturer (OEM) components, ensuring your gear performs exactly as it did the day you bought it.

Whether you are a professional fabricator maintaining your own rig or a shop manager keeping the fleet running, having a fresh diaphragm installed can make an old regulator feel brand new. It restores that crisp, responsive feel to your pressure adjustment knob and ensures your gas delivery is smooth and predictable. Keep your cuts clean and your shop safe with this essential repair component.

FAQ

Common symptoms include 'creep' (where the delivery pressure gauge rises after the torch valve is closed), audible leaking from the regulator bonnet, or erratic gas flow that makes it difficult to maintain a stable flame.

No, this specific assembly (999827) is designed for oxygen service. Oxygen and fuel gas components are often made of different materials and have different pressure ratings. Always use the part specified for the gas type.

Regulator repair should generally be performed by qualified technicians or individuals trained in gas equipment repair. Improper assembly of oxygen equipment can lead to dangerous leaks or hazards.

Oxygen supports combustion vigorously. OEM parts are manufactured and cleaned to strict standards to ensure they are free of oil and grease, which can ignite in a pure oxygen environment.

Typically, the diaphragm assembly includes the diaphragm material and the center plate/post. It usually does not include the main compression spring or the bonnet screws, which are reused unless damaged.

There is no set time, but regulators should be inspected annually. Diaphragms are typically replaced during a standard 5-year overhaul or whenever performance issues like creep or leaks are detected.

You will typically need a bench vise (with soft jaws) to hold the regulator body and a large wrench or socket to remove the bonnet. Cleanliness is critical during this process.
