OVERVIEW

ESAB 999827 Oxygen Regulator Diaphragm Assembly

The ESAB 999827 is a genuine OEM Diaphragm Assembly designed specifically for oxygen gas regulators. In the world of industrial gas control, the diaphragm is the critical sensing element that balances the downstream pressure against the regulator spring. Over time, diaphragms can lose elasticity, crack, or become fatigued, leading to issues such as pressure creep (where outlet pressure rises when flow stops) or external leaks. This replacement assembly allows technicians to rebuild the regulator to factory specifications, ensuring safe and reliable operation.

Constructed from materials strictly tested for oxygen compatibility, this assembly meets the rigorous safety standards required for oxy-fuel equipment. Using non-OEM or incompatible materials in oxygen service can present significant safety hazards, including the risk of fire. This ESAB part ensures that the chemical composition and mechanical properties match the original design requirements of your equipment.

This kit is essential for maintenance departments and repair shops servicing ESAB and Victor-style oxygen regulators. It typically includes the diaphragm disc and the associated center plate assembly, ready for installation into the regulator body. Proper installation restores the regulator's ability to maintain a steady delivery pressure regardless of cylinder pressure fluctuations.

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.
