20402279 - Tweco 174EX-1C Conduit Retaining Nut for MIG Guns

Genuine Tweco 174EX-1C Replacement Conduit Nut

Maintain the peak performance of your welding equipment with the Tweco 174EX-1C Conduit Nut (Stock No. 2040-2279). This component is a critical element in the wire feeding system of compatible Tweco MIG guns. Its primary function is to lock the wire conduit (liner) securely in place at the rear of the gun or within the power pin assembly. Without a secure conduit, the liner can float back and forth with the movement of the cable, leading to inconsistent wire stick-out, poor arc starts, and potential wire feeding failures.

Constructed from robust materials, typically brass, the 174EX-1C is designed to withstand the rigors of daily industrial use. It features precise threading that allows for easy installation and removal during liner changes, while still providing a lock-tight grip during welding. Professional welders know that the quality of the arc is directly related to the consistency of the wire feed. By ensuring your conduit is properly seated and retained with a fresh nut, you eliminate one of the common mechanical variables that can degrade weld quality.

This part is ideal for maintenance technicians and welders who perform their own equipment service. Regular inspection of the gun assembly often reveals wear on threads or rounded edges on retaining nuts. Replacing these small but significant parts proactively can prevent unexpected downtime in the middle of a job. The Tweco 2040-2279 is the direct OEM replacement, ensuring exact dimensional compatibility with your existing Tweco equipment.

Don't let a small hardware failure stop your production. Keep your MIG guns operating at factory standards with the Tweco 174EX-1C. It is a simple, cost-effective solution for extending the life of your torch and ensuring reliable wire delivery for every weld bead.
