94710027 - Arcair 94-710-027 O-Ring for K-4000 Torch (10-Pack)

Technical Overview of the Arcair 94-710-027 O-Ring

The Arcair 94-710-027 O-Ring is a critical replacement component designed specifically for the K-4000 Angle-Arc Gouging Torch. In the high-pressure environment of air carbon arc gouging, the integrity of the torch's internal sealing mechanisms is paramount. The K-4000 torch relies on a consistent stream of compressed air, typically ranging from 80 to 100 PSI, to effectively blow away molten metal generated by the carbon arc. Any compromise in the sealing system, such as a degraded or cracked O-ring, can lead to air leaks within the torch body or valve assembly. This results in reduced air pressure at the nozzle, inefficient metal removal, and potential overheating of the torch components.

This product is supplied as a package of 10, recognizing that O-rings are consumable wear items that require periodic inspection and replacement during routine maintenance. Manufactured to Arcair's precise specifications, these O-rings ensure a tight tolerance fit that generic substitutes may not provide. The material composition is selected to withstand the thermal cycling and environmental conditions typical of heavy industrial gouging operations. Proper installation of these O-rings restores the pneumatic efficiency of the torch, ensuring that the air valve operates smoothly and that the full volume of air is directed towards the arc zone.

Technicians and maintenance personnel responsible for the upkeep of gouging equipment understand that small components like O-rings play a disproportionately large role in equipment reliability. A leaking torch not only performs poorly but can also cause operator fatigue due to escaping air noise or erratic torch behavior. By utilizing genuine Arcair parts, users ensure the longevity of their K-4000 torches and maintain the safety and performance standards expected from the industry leader in air carbon arc gouging systems.
