OVERVIEW

Stop Fighting Your Wire Feed

If you are welding aluminum and your wire keeps stuttering, jamming, or bird-nesting, your liner is likely the culprit. The MK Products 615-0620-25 Teflon Conduit Assembly is the direct replacement you need to get your 25-foot MK push-pull gun running like new again. We all know that aluminum wire is soft and unforgiving; it hates friction. If your current liner is kinked, dirty, or worn out, the wire drags, the drive rolls slip (or shave the wire), and your arc starts sputtering. This fresh Teflon liner fixes that problem instantly by providing a slick, smooth highway for your wire to travel down.

Designed specifically for the 25-foot leads found on Cobramatic, Python, and Prince style systems, this assembly is ready to install. Why struggle with erratic feeding that ruins your bead appearance and frustrates you all day? A fresh liner is one of the cheapest and most effective maintenance tasks you can perform on your MIG gun. This isn't a generic knock-off; it's the real-deal MK part, meaning it fits your gun's back-end and front-end connections correctly without hacking or modification.

Whether you are building boat hulls, trailers, or signage, consistent wire feed is the key to those stack-of-dimes welds. Don't let a bad $50 part ruin a $5000 job. Keep a spare 615-0620-25 in your toolbox so you aren't caught waiting on shipping when your current liner finally gives up. Swap it out, blow out your cable, and get back to laying down smooth, clean aluminum welds.

FAQ

This conduit is made of Teflon (PTFE), which is ideal for reducing friction when feeding soft wires like aluminum.

The assembly is 25 feet long, designed for 25-foot cable assemblies.

While physically possible, Teflon liners are specifically designed for soft wires like aluminum. Steel wires are abrasive and will wear out a Teflon liner much faster than a steel spiral liner. It is recommended to use steel liners for steel wire.

Yes, this is the genuine MK Products 615-0620-25 Conduit Teflon Assembly.

Aluminum wire is soft and easily shaved by steel liners, causing clogging. Teflon provides a smooth, non-abrasive surface that allows the soft wire to slide easily without damage.

If you experience erratic wire feeding, burn-back, or notice the wire is difficult to push through the cable by hand, it is likely time to replace the conduit.

It fits many MK Products push-pull systems with 25-foot cables, such as certain configurations of the Python, Prince, and Cobramatic lines. Always check your specific gun's parts manual to confirm the part number.

This is typically the conduit assembly itself. Depending on the specific revision, it may include attached ferrules or o-rings required for seating in the gun/feeder. Refer to the product image or manual for exact contents.
