82Z52 - ESAB 82Z52 Regulator Inlet Filter Screen (Pack of 5)

Precision Filtration for Gas Regulation Systems

The ESAB 82Z52 Inlet Filter Screen is a critical maintenance component designed to ensure the longevity and accuracy of industrial gas regulators. Supplied in a convenient pack of 5, these screens are engineered to fit a wide range of ESAB, Purox, and Oxweld regulators. The primary function of the inlet screen is to act as the first line of defense against contaminants that may be present in gas cylinders or supply lines.

Gas regulators rely on precision-machined seats and stems to control high-pressure gas flow. Even microscopic particulate matter, such as rust, scale, or dust from a cylinder valve, can lodge between the seat and the nozzle. This intrusion can cause "creep," where delivery pressure rises dangerously when the torch is off, or permanent damage to the regulator seat. By installing a fresh 82Z52 screen, operators ensure that only clean gas enters the regulator body, thereby preserving the integrity of the internal sealing mechanisms.

These screens are manufactured from durable metal mesh, capable of withstanding the high-velocity impact of incoming gas while maintaining sufficient flow rates for cutting and welding applications. Regular inspection and replacement of the inlet filter are recommended as part of a standard preventative maintenance schedule. A clogged screen can restrict flow, leading to flame instability or starvation, while a missing screen invites catastrophic regulator failure. This 5-pack ensures that maintenance personnel have the necessary spares on hand to service multiple units or perform successive changes.

Technical Compatibility

The 82Z52 is the standard replacement screen for numerous legacy and current regulator series within the ESAB family, including popular Purox and Oxweld models. It is designed to fit snugly within the inlet nipple, ensuring no bypass of unfiltered gas occurs.
