OVERVIEW

Keep Your Arc Smooth with Tweco Velocity Sleeves

When you are in the middle of a long weld, the last thing you need is your front-end consumables failing or overheating. The Tweco 1640-1397 Velocity Threaded Sleeve (VCTLSL) is the backbone of your Tweco Fusion MIG gun's front end. This pack of 5 replacement sleeves ensures you have the parts you need to keep your torch running at peak performance. The Velocity system is famous for staying cool under pressure, and this sleeve is what makes that possible by connecting your conductor tube to the tip and nozzle with a solid, high-conductivity copper link.

Over time, heat and spatter can wear down even the toughest parts. Replacing your threaded sleeve is a simple maintenance step that can drastically improve your gas coverage and arc stability. A worn sleeve can lead to poor gas flow, erratic arcs, and frustrating downtime. By swapping in a fresh VCTLSL sleeve, you restore the proper gas diffusion pattern and ensure your contact tip is seated perfectly centered. This means less spatter, better bead appearance, and less time troubleshooting your gun.

Designed for professional welders who demand reliability, these sleeves are easy to install and built to last. They fit perfectly with Tweco's Velocity contact tips and nozzles, creating a tight seal that prevents gas leakage. Whether you are welding mild steel, stainless, or aluminum, having a fresh sleeve in your kit is essential for maintaining quality welds. Don't let a worn-out diffuser ruin your day—stock up on these genuine Tweco sleeves and keep burning wire without interruption.

Why Choose Genuine Tweco Parts?

  • Perfect Fit: Guaranteed compatibility with your Velocity setup.
  • Better Cooling: Solid copper design pulls heat away from the tip.
  • Consistent Gas Flow: Engineered to smooth out shielding gas turbulence.
  • Durability: Resists thread galling and heat deformation.

FAQ

The VCTLSL threaded sleeve acts as the interface between the conductor tube and the contact tip/nozzle, functioning similarly to a gas diffuser by directing shielding gas and conducting current.

This package contains 5 Tweco Velocity threaded sleeves.

It is compatible with Tweco guns that are equipped with the Velocity™ consumable system, such as the Tweco Fusion™ series. It does not fit standard Tweco No. 2 or No. 4 guns unless they have been converted.

The sleeve is made of a high-conductivity copper alloy to manage heat and electrical transfer efficiently.

You should replace the sleeve if the threads become damaged, if it is clogged with spatter that cannot be removed, or if you notice gas coverage issues and arc instability.

Yes, it can be used with flux-cored wires, provided you are using the appropriate Velocity contact tips and nozzles for the application.

The part number is 1640-1397, and the stock code is VCTLSL.
