0365803017 - ESAB Blue Water Quick Connector 6.3mm

Reliable Coolant Connections for Your ESAB Equipment

Maintaining the integrity of your water-cooling system is critical for high-amperage welding applications. The ESAB Quick Coupling Blue 6.3mm (SKU: 0365803017) is a genuine replacement part designed to restore the functionality of your ESAB water cooler or welding power source. Over time, the O-rings and locking mechanisms in quick connectors can wear down due to frequent connecting and disconnecting of TIG or MIG torches. A worn connector often leads to frustrating leaks, coolant loss, and potentially overheating your expensive torch cables.

This specific coupling is color-coded Blue, which typically designates the coolant supply (water out) line in standard welding setups. This visual cue is essential for welders setting up their gear quickly, ensuring that the cold water flows in the correct direction through the torch head. The 6.3mm size is a standard specification for many ESAB machines, ensuring a snug, leak-free fit with compatible male nipples found on torch hoses.

Whether you are repairing a shop machine or performing maintenance on a portable unit like the ESAB CoolMini, using genuine OEM parts is the best way to guarantee performance. Generic fittings may look similar but often lack the precise tolerance required to hold pressure under the vibration and heat of an industrial environment. This coupling features a robust panel-mount design, allowing it to be securely fixed to the machine chassis, providing a stable connection point for your welding operations.

Don't let a dripping connector slow down your production or compromise your weld quality. Swapping out a damaged coupling is a quick maintenance task that protects your equipment investment. This ESAB blue quick coupling offers the durability and reliability professional fabricators expect from the brand.
