94173044 - Arcair 94-173-044 Knurled Coupling for K-Series Torches

Technical Overview of the Arcair 94-173-044 Coupling

The Arcair 94-173-044 is a specialized knurled coupling designed specifically for the assembly and maintenance of Arcair K-Series angle-arc gouging torches. This component plays a critical role in the structural and functional integrity of the torch system, serving as the primary mechanical interface between the torch body and the concentric cable assembly. Manufactured to precise OEM tolerances, this coupling ensures that both the electrical current path and the compressed air stream are maintained without interruption or leakage.

Constructed from high-grade brass, the coupling offers excellent conductivity and resistance to the thermal cycling inherent in carbon arc gouging processes. The exterior features a distinct knurled pattern, engineered to facilitate secure tightening by hand or with minimal tool assistance, even when the operator is wearing protective gloves. This part is essential for technicians repairing or refurbishing K2000, K3000, or K4000 torches, ensuring that the torch handle remains firmly attached to the power and air supply.

Failure of the coupling due to thread wear or mechanical damage can lead to loose connections, arcing at the joint, or loss of air pressure, all of which compromise the efficiency and safety of the gouging operation. Replacing a worn coupling with this genuine Arcair part restores the torch to factory specifications.
