22355 - ESAB 22355 Replacement Seat Assembly for R-6700 Regulators

Precision Replacement for Heavy-Duty Gas Control

The ESAB 22355 Seat Assembly is an essential maintenance component engineered specifically for the renowned R-6700 series of industrial gas regulators. As the primary sealing mechanism within the high-pressure chamber, the seat plays a pivotal role in modulating gas flow from the cylinder to the delivery line. Over time, the extreme pressures and frequent cycling inherent in welding and cutting operations can cause the seat material to degrade, leading to performance issues. This genuine OEM part ensures that your equipment continues to operate within its original factory specifications.

Constructed from high-grade materials compatible with various industrial gases, the 22355 assembly is designed to withstand the mechanical stress of the regulator's valve stem. A compromised seat is the leading cause of "regulator creep," a condition where delivery pressure rises uncommanded when the downstream valve is closed. Replacing the seat with this authentic ESAB component effectively resolves this safety hazard, ensuring stable pressure delivery and protecting downstream equipment from over-pressurization.

Maintenance professionals understand that using genuine parts is critical for liability and safety, especially when dealing with high-pressure oxygen and fuel gases. The ESAB 22355 offers the exact dimensional tolerances required for the R-6700 body, ensuring a leak-free seal and smooth adjustment characteristics. Whether performing routine preventative maintenance or an emergency repair, this seat assembly is the standard for restoring R-6700 regulators to peak operational condition.
