22358 - ESAB 22358 Teflon Friction Ring for R-6700 Regulators

Technical Overview of the ESAB 22358 Teflon Ring

The ESAB 22358 is a specialized Teflon (PTFE) ring designed specifically for the bonnet assembly of R-6700 series regulators. In high-pressure gas regulation equipment, the mechanical interaction between the adjusting screw, the spring button, and the bonnet housing is critical for precise pressure delivery. This component serves as a low-friction interface, often acting as a slip ring or friction washer that facilitates the smooth rotation of the adjusting key or knob while under spring tension.

Manufactured from high-quality Polytetrafluoroethylene (PTFE), this ring offers exceptional resistance to chemical degradation and environmental wear, which is essential in industrial welding environments. The material's low coefficient of friction prevents galling and binding, ensuring that operators can make fine adjustments to outlet pressure without experiencing "stick-slip" phenomena. As a genuine ESAB part (inheriting the legacy of Oxweld/Purox heavy-duty equipment), the 22358 ring meets strict dimensional tolerances that generic substitutes may fail to achieve.

Proper maintenance of the R-6700 series regulator involves periodic inspection of internal wear components. A worn or damaged Teflon ring can lead to difficulty in pressure adjustment or inconsistent spring compression. Replacing this ring during a standard overhaul restores the tactile feedback and precision of the regulator, extending the service life of the entire unit. This part is a direct replacement for the original factory component, ensuring seamless integration into the regulator assembly.
