34Y01 - ESAB 34Y01 Valve Seat Assembly for Oxweld Regulators

Restore Precision Control with the ESAB 34Y01 Valve Seat Assembly

The ESAB 34Y01 Screw Clamping Valve Seat Assembly is a critical replacement component designed for the maintenance and repair of heavy-duty industrial gas regulators. Manufactured to the exacting standards of ESAB (formerly Oxweld and Purox), this valve seat is the heart of the regulator's pressure control mechanism. Over time, the seating surface within a regulator can wear down, degrade from debris, or harden, leading to "creep"—a dangerous condition where outlet pressure rises when the torch valves are closed. Installing a genuine 34Y01 seat ensures that your equipment operates safely and within its specified pressure ranges.

This assembly is specifically engineered for compatibility with the legendary Oxweld R-Series regulators, including the R-72, R-76, and R-77 models, which are staples in heavy fabrication and scrap industries. The part features precision-machined brass components and high-quality sealing materials that resist the harsh environment of high-pressure gas flow. By replacing a worn seat with this OEM part, you not only extend the lifespan of your valuable apparatus but also ensure the safety of the operator by preventing regulator failure.

Maintenance professionals understand that using generic parts in high-pressure gas equipment can compromise performance. The ESAB 34Y01 guarantees the correct fitment and material compatibility required for oxygen and fuel gas service. Whether you are rebuilding a vintage Oxweld unit or maintaining a fleet of shop regulators, this valve seat assembly provides the reliability and performance associated with the ESAB brand.
