OVERVIEW

Reliable Regulator Repair with ESAB 20345

Keep your welding and cutting operations running smoothly with the ESAB 20345 Diaphragm Assembly. This replacement part is the heart of your gas regulator, responsible for controlling the flow and pressure of gas from the cylinder to your torch or machine. When a diaphragm fails, it can lead to erratic gas flow, leaks, or the inability to adjust pressure, all of which bring work to a halt.

Designed for professional welders and fabricators, this ESAB diaphragm assembly offers a direct replacement solution that is both cost-effective and reliable. Instead of replacing an entire regulator, swapping out the diaphragm can often return the unit to like-new performance. The component is built to withstand the rigors of daily shop use, featuring robust construction that resists drying out or cracking under pressure.

Installation is straightforward for those experienced in regulator repair, allowing you to get your equipment back in service quickly. By choosing the ESAB 20345, you are investing in the safety and efficiency of your gas delivery system. Ensure your flame remains stable and your shield gas coverage stays constant by maintaining your regulators with high-quality OEM components.

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.
