57N75XXL - CK 57N75XXL #6 Alumina Nozzle for Large Gas Lens (3-Inch Long)

Technical Overview: CK Worldwide 57N75XXL

The CK Worldwide 57N75XXL is a specialized alumina oxide nozzle designed for precision TIG welding applications requiring extended reach and superior gas coverage. This component is engineered to interface with Large Diameter Gas Lens collet bodies (such as the 45V64, 45V116, etc.) commonly used on 17, 18, and 26 series TIG torches. The 'XXL' designation indicates a 3-inch (76.2mm) overall length, significantly longer than standard nozzles, facilitating access to recessed weld joints and complex geometries.

Manufactured from high-grade alumina ceramic, this nozzle offers excellent thermal shock resistance and durability under high-amperage conditions. The #6 orifice (3/8-inch / 9.5mm) provides a concentrated column of shielding gas, which, when conditioned by the gas lens screen, ensures laminar flow. This reduces turbulence and minimizes the risk of atmospheric contamination, even with the increased stick-out often required when using extended nozzles.

This nozzle is an essential component for industrial fabrication environments where standard cups cannot provide adequate clearance or visibility. It maintains compatibility with standard industry threads for large gas lenses, ensuring seamless integration into existing equipment inventories.
