ESAB Rubber Plug .375 x .250 (Pack of 2)

Keep Your Welder Sealed and Clean

We've all been there—you're looking over your rig and notice a small hole where a plug used to be. Maybe it popped out during a move, or maybe it just dried up and fell apart years ago. You might think, "It's just a little hole, what's the big deal?" But in a welding shop, that little hole is an open door for grinding dust, metal shavings, and moisture to get right inside your machine. The ESAB 950423 Rubber Plug is the exact replacement you need to close that door and keep your internals clean.

This isn't just any piece of rubber; it's a genuine ESAB part sized perfectly at 0.375" diameter and 0.250" length. If you try to jam a random piece of plastic or tape in there, it's eventually going to fail. This plug is designed to pop in snugly and stay there. The rubber material gives it enough grip to handle the vibration of a running welder without working itself loose. It also creates a tight seal that keeps the bad stuff out, protecting your circuit boards and wire drive mechanisms from the gritty reality of the shop floor.

These plugs come in a convenient 2-pack. This is great because if you've lost one, chances are you might lose another down the road, or maybe you have two spots that need attention. Having a spare in your toolbox means you're ready the next time you do a maintenance check. It’s a cheap and easy fix that can save you from expensive repairs caused by shorted boards or clogged fans later on.

Don't let your professional equipment look like a beat-up jalopy with missing parts. Replacing missing plugs shows you care about your tools. It takes two seconds to install: just push it in, and you're good to go. Whether you are fixing up an old feeder or just replacing a plug that's seen better days, the ESAB 950423 is the right part for the job. Keep your machine sealed, safe, and running like a champ.
