22481 - ESAB R-6702 Regulator Pressure Adjusting Spring

Precise Control for R-6702 Regulators

The ESAB 22481 Adjusting Spring is a critical replacement component designed specifically for the R-6702 series of gas regulators. In industrial gas control systems, the adjusting spring plays a vital role in counterbalancing the forces on the diaphragm, allowing the operator to set the desired outlet pressure with precision. Over time, springs can suffer from fatigue, corrosion, or plastic deformation, leading to erratic pressure delivery or the inability to reach maximum pressure settings. Replacing a compromised spring with this genuine OEM part ensures that the regulator performs within its original design specifications.

Manufactured from high-grade spring steel, this component is engineered to maintain consistent spring rates over a wide range of compression. This consistency is essential for applications requiring stable gas flow, such as oxy-fuel cutting, heating, and welding. Using non-OEM springs can result in incorrect pressure ranges or non-linear adjustment behavior, which can compromise process quality and safety. The ESAB 22481 ensures a direct fit within the regulator bonnet, seating correctly against the pressure adjusting screw and the diaphragm plate.

Maintenance personnel and technicians repairing Purox or ESAB R-6702 regulators rely on genuine parts to extend the service life of this durable equipment. This spring is part of the internal mechanism that should be inspected during routine regulator overhauls. If the existing spring shows signs of rust, pitting, or permanent set (loss of height), immediate replacement is recommended to restore full functionality and safety to the gas delivery system.
