264581 - Miller 146mm Neck Liner D4x7

Keep Your Feed Smooth with the Miller 264581 Liner

If you are experiencing stuttering wire or erratic feeding at the torch end, it might be time to check your neck liner. The Miller 264581 is a 146mm replacement liner designed to fit specific Miller MIG guns. Often called a "jump liner," this short piece sits inside the curved neck of your gun—the area that takes the most abuse from heat and wire friction. Over time, this liner can get clogged with debris or worn down by the wire, causing friction that ruins your weld consistency.

Swapping out a worn neck liner is a quick fix that can save you hours of frustration. This genuine Miller part features D4 x 7 dimensions, ensuring a perfect fit inside your torch head without rattling or gas leakage. It provides a smooth, low-friction tunnel for your welding wire right before it hits the contact tip. Whether you are running solid wire or flux-cored, keeping this short liner fresh is key to preventing burn-backs and birdnesting.

Don't let a cheap consumable hold up your production. Keep a few Miller 264581 liners in your toolbox so you can swap them out the moment you feel drag in the gun. It’s a small part that plays a huge role in getting that buttery-smooth bead you’re looking for. Compatible with select Miller guns requiring a 146mm liner segment.
