22356 - ESAB 22356 Seat Holder for R-6700 Regulators

Precision Engineering for High-Capacity Gas Control

The ESAB 22356 Holder Seat is a critical replacement component designed exclusively for the R-6700 series of heavy-duty industrial gas regulators. In the realm of high-flow gas regulation, the integrity of internal components is paramount to maintaining safety and operational efficiency. The R-6700 series is renowned for its ability to handle substantial flow rates and pressures, often found in steel mills, foundries, and heavy fabrication environments. This holder seat plays a vital role in the internal mechanics of the regulator, specifically in securing and aligning the seat assembly against the nozzle.

Manufactured to exact OEM specifications, this part ensures that the sealing mechanism operates without deviation. Over time, internal regulator components are subjected to mechanical stress and high-velocity gas flow, which can lead to wear. A compromised holder seat can result in misalignment, leading to "creep"—a dangerous condition where delivery pressure rises when the downstream valve is closed—or external leaks. By utilizing the genuine ESAB 22356, maintenance personnel can restore the regulator to its original factory tolerances, ensuring consistent delivery pressure and extending the service life of the equipment.

This component is machined from high-quality brass, selected for its durability and compatibility with various industrial gases. It is engineered to withstand the rigors of daily industrial use, providing a stable platform for the regulator's sealing elements. When performing a scheduled overhaul or emergency repair on an R-6700 unit, replacing the holder seat is a standard procedure to guarantee the reliability of the reassembled device. Trusting genuine ESAB parts safeguards your equipment investment and ensures compliance with safety standards.

Technical Significance

The interaction between the seat, the nozzle, and the holder is the heart of the pressure reduction process. Even microscopic imperfections in these mating surfaces can compromise performance. The 22356 Holder Seat is finished to strict dimensional standards to ensure a perfect interface, preventing gas bypass and ensuring smooth pressure adjustment response.
