94168022 - Arcair SLICE Torch 1/4 Inch Collet Nut Replacement Part

Technical Overview of the Arcair 1/4" Collet Nut Assembly

The Arcair 1/4" Collet Nut Assembly (SKU: 94168022) is a critical component designed specifically for the Arcair SLICE exothermic cutting torch system. As an Original Equipment Manufacturer (OEM) replacement part, it is engineered to meet the precise dimensional and material specifications required for safe and efficient operation of the SLICE torch. This assembly serves as the primary retention mechanism for 1/4-inch exothermic cutting rods, ensuring they are seated firmly against the internal washer and collet for optimal electrical conductivity and oxygen flow.

In the context of the SLICE torch assembly diagram, this component is identified as Part #4. It threads onto the torch head, compressing the collet to grip the cutting rod. The integrity of this connection is vital; a loose or damaged nut can lead to arcing inside the head, gas leaks, or rod slippage, all of which compromise the safety and effectiveness of the cutting process. The assembly is manufactured from high-grade materials capable of withstanding the radiant heat generated during exothermic cutting, where temperatures at the rod tip can exceed 10,000°F.

Maintenance professionals and procurement specialists should verify the rod diameter currently in use before ordering. The SLICE system is versatile and can accept different rod sizes; this specific nut assembly is dedicated to the 1/4-inch configuration. Regular inspection of the collet nut for thread wear, heat distortion, or physical damage is recommended as part of a preventative maintenance schedule for industrial cutting equipment.
