22405 - ESAB R-76 Regulator Gaugeless Cup Adapter / Cover

Genuine ESAB Replacement for R-76 Series Regulators

The ESAB 22405 Gaugeless Cup Adapter is a critical replacement component designed specifically for the R-76 series of industrial gas regulators. Manufactured to ESAB's exacting standards, this part serves as the upper housing or adapter for regulators configured without standard pressure gauges. In heavy-duty industrial environments—such as scrap yards, demolition sites, and steel mills—external gauges are often the first components to fail due to impact or rough handling. By utilizing a gaugeless configuration with this cup adapter, operators can maintain a more robust and streamlined regulator assembly that is less susceptible to external damage.

This adapter is precision-machined from high-quality brass, ensuring compatibility with the R-76 body and internal components. It provides the necessary housing for the internal pressure-adjusting mechanism while sealing the upper portion of the regulator against environmental contaminants. For maintenance professionals and equipment repair specialists, using genuine OEM parts like the 22405 is essential to preserving the pressure rating, flow characteristics, and safety certifications of the original equipment. Improperly fitted aftermarket parts can lead to gas leaks or pressure creep, posing significant safety hazards in oxy-fuel applications.

Installation of the Gaugeless Cup Adapter should be performed by qualified personnel familiar with high-pressure gas equipment. The part integrates seamlessly with the existing bonnet and spring assembly of the R-76. Whether you are rebuilding an older unit or converting a standard regulator for specific field applications, this adapter ensures that your ESAB equipment continues to perform with the reliability and precision expected from the brand.
