16401371 - Tweco Spray Master MS64 Series Conductor Tube Replacement

Restore Your Spray Master's Performance

Every welder knows that the neck of the MIG gun takes the most abuse. It gets banged against tables, splattered with hot metal, and subjected to intense heat cycle after cycle. If your Tweco Spray Master gun is starting to feel sluggish, or if you are noticing erratic arcs and feeding issues, it might be time to check your conductor tube. The Tweco 1640-1371 (MS64-SFLX-480EL) is the genuine replacement neck you need to get your equipment back to factory-fresh performance. Don't struggle with a bent or clogged neck that ruins your bead profile; swapping out this component is a quick fix that makes a massive difference.

Designed specifically for the Spray Master series, this conductor tube offers the perfect balance and angle you are used to. The "Spray Master" name is synonymous with heavy-duty performance, and this tube lives up to that legacy. It features a heavy-duty copper construction that handles the heat of high-amp spray transfer welding without breaking a sweat. The insulation is tough enough to resist cuts and abrasion, keeping you safe and your gun operational in rough shop environments. Whether you are welding structural steel, heavy equipment, or pipe, having a reliable current path to your contact tip is non-negotiable.

Installation is straightforward, allowing you to get back under the hood quickly. A fresh conductor tube not only improves electrical conductivity but also ensures your gas flow is laminar and your wire feeds smoothly without drag. This translates to less spatter, better penetration, and less frustration at the end of the day. Keep a spare MS64-SFLX-480EL in your toolbox or supply locker so you are never caught off guard by a damaged gun. Trust Tweco's engineering to keep your welds clean and your downtime to a minimum.
