18859 - 2-1/4 Inch Threaded Replacement Gauge Lens

Professional Grade Regulator Maintenance

The ESAB 18859 Crystal 2-1/4 Turn is a critical maintenance component designed for the repair and refurbishment of industrial gas regulators. In the field of welding and gas distribution, the integrity of pressure monitoring equipment is paramount for both safety and process consistency. Over time, the protective lenses on pressure gauges can become cracked, scratched, or clouded due to exposure to harsh industrial environments, impact, or chemical fumes. This replacement crystal restores the functionality of the gauge, ensuring that operators can accurately read cylinder and delivery pressures without obstruction.

Manufactured from high-grade, impact-resistant polycarbonate, this lens offers superior durability compared to standard glass or lower-quality plastics. It is engineered to withstand the mechanical shocks typical of busy workshops and mobile welding rigs. The 2-1/4 inch diameter is a standard sizing specification for many medium-to-heavy-duty regulators, including those in the Victor and ESAB product lines. The "Turn" designation indicates a threaded bezel design, which simplifies the replacement process. Unlike snap-in lenses that may require prying and potential damage to the gauge housing, this threaded crystal screws securely into place, providing a tight seal against dust, moisture, and particulate matter.

Maintaining clear visibility of pressure gauges is not merely a convenience; it is a safety requirement. An obscured gauge can lead to misinterpretation of gas levels, potentially resulting in running out of shielding gas mid-weld or, more dangerously, failing to notice over-pressure situations. By utilizing the ESAB 18859 replacement crystal, maintenance personnel can extend the service life of expensive regulator assemblies, ensuring compliance with safety standards and maintaining operational efficiency. This component is an essential stock item for MRO (Maintenance, Repair, and Operations) inventories in fabrication shops, shipyards, and manufacturing facilities.
