32Z49 - ESAB 32Z49 Valve Seat Assembly for R-201 Series Regulators

Precision Regulator Repair Component

The ESAB 32Z49 Seat Valve Assembly is a critical replacement component designed specifically for the maintenance and repair of Purox and ESAB R-series regulators, including the widely used R-201, R-202, and R-203 models. As a genuine OEM part, it is manufactured to the exact tolerances required to maintain the safety and performance standards of the original equipment. The valve seat plays a pivotal role in the regulation of gas pressure, acting as the primary sealing interface that controls the flow of gas from the high-pressure cylinder to the low-pressure delivery side.

Over time, the elastomeric sealing surface of a valve seat can degrade due to wear, debris, or the high-velocity impact of gas during opening cycles. This degradation often manifests as "creep," where delivery pressure rises unintentionally when the torch valves are closed. Replacing the seat assembly with the 32Z49 ensures a positive seal is re-established, effectively halting pressure creep and restoring the regulator's ability to hold a steady dynamic pressure. The assembly features a precision-machined brass body that resists corrosion and ensures proper alignment within the regulator body.

Industrial maintenance professionals rely on genuine ESAB parts to ensure compliance with safety protocols. Using aftermarket or ill-fitting seats in high-pressure gas equipment can lead to catastrophic failures or inconsistent flow rates. This assembly is supplied ready for installation, ensuring that your oxy-fuel or inert gas equipment returns to operational status with minimal downtime.
