MM211 o-rings

[labmaster02]

I have a MM211 and I change between the spool gun and the standard gun. It's a tight fit going into the welder. I noticed today one of the o-rings was torn. Is there any recommendations for lube on these o-rings?

I have used the Syncolon on O-Rings.

Loctite brand Silicone Lubricant (their part number is 51360) may be just what you need...that number is for a 5.3 ounce tube and is something I keep in my toolbox for use on rubber stuff that needs some kind of slickum on it.

Use a very thin coat of high-quality silicone grease like NAPA Sil-Glyde, Ford Caliper/Dielectric, or Ford Electrical.

.

I also use it on my bottle fittings to help prevent tiny leaks & prevent corrosion/seizing.
