227421 - Miller 227421 Compression Spring .360 OD x .440 Free (10-Pack)

Keep Your Torch Running Smoothly

Every welder knows the frustration of equipment that doesn't feel right. Maybe the trigger is sticking, or a locking mechanism isn't holding as tight as it should. Often, these annoying issues come down to a single, small component: a worn-out spring. The Miller 227421 Compression Spring is the genuine replacement part you need to get your Miller or Tregaskiss MIG gun back to feeling brand new. Don't let a fifty-cent problem cause a hundred-dollar headache; replacing tired springs is one of the easiest and most effective ways to maintain your gear.

This specific spring is built tough for the industrial environment. With an outer diameter of 0.360 inches and a sturdy 0.059-inch wire thickness, it provides the firm, reliable tension your equipment was designed to have. Unlike generic hardware store springs that might be too soft or the wrong size, this OEM part is calibrated perfectly for your welding torch. It fits exactly where it's supposed to, ensuring that triggers reset crisply and internal parts stay seated securely. When you pull the trigger, you want a consistent response, and a fresh spring is key to that tactile feedback.

We know that in a busy shop, parts have a way of disappearing. That is why the Miller 227421 comes in a convenient pack of 10. Having a stash of spare springs in your toolbox or maintenance locker means you are always prepared. If a spring flies across the shop floor during a repair—and we have all been there—you won't have to stop production to order a replacement. You can simply grab another one from the pack and get back to welding. It is a small investment that pays off in reduced downtime and less frustration.

Maintenance is part of the job, but it doesn't have to be a chore. Swapping out a compression spring is usually a quick fix that requires minimal tools. By keeping your MIG gun maintained with high-quality, genuine Miller parts, you extend the life of the entire torch and ensure that your focus stays on laying perfect beads, not fighting with your equipment.
