HALANSM® Premium Replacement Coupler for Powermax 125

Ensure the structural integrity and cooling efficiency of your plasma torch with the HALANSM 428248 Coupler. This small but vital component is often the unsung hero in plasma cutting systems, preventing leaks and ensuring consistent arc stability.


Key Functions:

  • Secure Assembly: The precisely cut external threads allow the coupler to lock firmly into the torch body, preventing the retaining cap from backing off during operation.

  • Water Cooling Path: The internal cavity and o-ring groove work together to create a closed-loop water channel, critical for cooling the electrode and nozzle during high-amperage cuts.

  • Vibration Dampening: Helps absorb mechanical stress transmitted through the torch head during drag cutting or gouging.


Compatibility Guide:

This coupler is a direct replacement for the original equipment manufacturer (OEM) part 428248. It is specifically designed for the Powermax 125 / Duramax 125 system and interfaces correctly with associated consumables like the 220971 electrode and 220975 nozzle.


Disclaimer: This product is manufactured by HALANSM as a compatible replacement part. It is not created or endorsed by Hypertherm Inc. as an OEM product.
