OVERVIEW

Genuine Bernard R402-4 Retaining Ring (2-Pack)

Maintain the structural integrity and performance of your Bernard MIG welding guns with the Bernard R402-4 Retaining Ring. This essential replacement part is designed to secure the gas diffuser and nozzle assembly, ensuring that your consumables remain firmly in place during high-heat welding operations. Over time, retaining rings can lose their tension due to repetitive thermal cycling or can be easily misplaced during routine cleaning and maintenance. This convenient 2-pack ensures you always have a spare on hand, minimizing downtime in your production line.

The R402-4 is engineered to meet Bernard's strict manufacturing standards, providing a precise fit that aftermarket alternatives often fail to match. A loose nozzle or diffuser can lead to inconsistent gas coverage, porosity in the weld, or even electrical arcing where it shouldn't occur. By replacing worn retaining rings with genuine Bernard parts, you ensure that the shielding gas flows directly to the weld pool without turbulence caused by loose components. This small but critical component plays a vital role in the overall efficiency of your MIG gun setup.

Installation is straightforward, allowing operators to swap out old rings quickly without specialized tools. Whether you are running a heavy industrial fabrication shop or a smaller welding operation, keeping your equipment in top condition is key to quality output. The Bernard R402-4 is compatible with various Bernard gun models, making it a versatile addition to your maintenance inventory. Trust in the durability and reliability of genuine Bernard parts to keep your welders welding.
