OVERVIEW

Restore Precision with the ESAB 20345 Diaphragm Assembly

The ESAB 20345 Diaphragm Assembly is a critical replacement component designed to maintain the accuracy and safety of your gas regulation equipment. As a genuine OEM part, it is engineered to meet the exact specifications of compatible ESAB regulators, ensuring a perfect fit and reliable performance. The diaphragm plays a central role in balancing internal pressures, allowing for the smooth and consistent delivery of shielding or cutting gases.

Over time, regulator diaphragms can lose elasticity or develop micro-cracks due to constant flexing and exposure to pressurized gases. Replacing a worn diaphragm with the ESAB 20345 restores the regulator's ability to hold a steady outlet pressure, preventing fluctuations that can compromise weld quality or cutting precision. This assembly is manufactured from high-quality materials resistant to gas permeation and environmental wear, providing long-lasting durability in industrial environments.

Whether you are performing routine maintenance or repairing a malfunctioning unit, using genuine ESAB parts like the 20345 Diaphragm Assembly guarantees that your equipment continues to operate within safety standards. It is an essential spare part for maintenance departments and welding shops looking to extend the lifecycle of their oxy-fuel or shielding gas regulators.

FAQ

The diaphragm acts as the sensing element in a gas regulator, balancing the spring force against the gas pressure to maintain a constant outlet flow.

Signs include creeping pressure on the gauge when the torch is off, gas leaks from the regulator body, or an inability to adjust the pressure smoothly.

Yes, the ESAB 20345 is a genuine OEM replacement part manufactured by ESAB.

Regulator repair should only be performed by qualified personnel or certified repair technicians to ensure safety and proper calibration.

This part is designed for specific ESAB and legacy brand (like Purox or Oxweld) regulators. Please check your equipment's parts manual for compatibility.

This item is typically the diaphragm assembly itself. Check the specific contents or your regulator's diagram to see if separate gaskets are required.

OEM parts ensure the correct material compatibility and dimensional tolerances, which are critical for preventing high-pressure gas leaks.
