0558011006 - ESAB 720 Series Regulator Pressure Adjustment Screw

Precise Control for Industrial Gas Regulation

The ESAB 0558011006 Pressure Adjustment Screw is a critical replacement component designed specifically for the 720 series of industrial gas regulators. In the architecture of a pressure regulator, the adjustment screw serves as the primary mechanical actuator, translating rotational torque into linear force that compresses the range spring against the diaphragm assembly. This interaction is fundamental to setting the outlet pressure of the device. Over time, the threads on an adjustment screw can suffer from wear, deformation, or galling, particularly in high-cycle environments where pressure settings are frequently modified. A compromised screw can lead to erratic pressure adjustments, "sticky" operation, or the inability to achieve the desired flow rate.

Manufactured to exact OEM specifications, this screw ensures correct thread pitch and diameter, guaranteeing a seamless mate with the regulator bonnet. Using non-OEM parts in this application can result in thread damage to the regulator body, rendering the entire unit unusable. This component is engineered from high-grade materials capable of withstanding the significant back-pressure exerted by heavy-duty regulator springs. It is an essential spare part for maintenance departments and repair technicians tasked with refurbishing or maintaining the operational integrity of ESAB and Victor 720 series gas control equipment.

Proper installation of this screw restores the tactile feedback and precision required for fine-tuning gas delivery, whether for oxy-fuel cutting, welding shielding gas, or purging applications. It represents a cost-effective solution to extend the service life of high-value regulation equipment.
