16401398 - Tweco VNC-F Velocity Nozzle Collar

Tweco 1640-1398 VNC-F Nozzle Collar for Velocity MIG Guns

Keep your Tweco MIG gun performing at its best with the Tweco 1640-1398 Velocity Nozzle Collar (VNC-F). This replacement collar is an integral part of the revolutionary Velocity consumable platform, known for its superior arc stability and extended consumable life. The nozzle collar is designed to thread securely onto the conductor tube, providing a robust mounting point for the Velocity gas nozzle. Its robust design ensures that your nozzle stays perfectly aligned, which is crucial for maintaining consistent gas coverage and preventing weld defects.

One of the standout features of the Velocity system is its ability to run cooler and last longer than traditional front-end consumables. The VNC-F collar contributes to this performance by facilitating efficient heat transfer and maintaining a tight seal. Over time, the threads on a nozzle collar can become worn or damaged from frequent nozzle removal and spatter cleaning. Replacing a worn collar with a new 1640-1398 unit restores the mechanical integrity of your gun's front end, preventing gas leaks and ensuring that your nozzle remains firm and stable during operation.

Installation is straightforward and requires no special tools, allowing welders to swap out the part right at their station. The brass construction is tough enough to handle the rigors of daily shop use, including exposure to high amperage arcs and reflective heat. This collar is compatible with a wide range of Tweco guns that utilize the Velocity system, including the popular Spray Master series. By using OEM parts, you ensure that the dimensions and tolerances are exact, avoiding the fitment issues often seen with aftermarket copies.
