    What is the grease product for lubricating O-Rings on fill probes?

    I think there is controversy about this, and I'm no expert, so you need to continue your research. I think the basic variables of use and material are very important; high pressure or not, static or moving surfaces. The only thing I use on O rings is pure, food grade silicone, and not much. Again, whether that is best, I'm not sure, but it seems to work for me.

    Most “experts” say not to use anything on fill probe o rings, just replace when necessary.  Personally, I use a tiny bit of divers silicone on mine once in awhile and keep them out of the dirt.

    I would also suggest a *Silicone based lubricant.
    The *Silicone based lubes aren't destructive, and will help soften the o-ring/rubber.

    That'ss what I've used exclusively [in my auto / custom shops] for 15+ years w/ no issues.
    I've also used a few Teflon based lubes on my own applications, but only when silicone based wasn't on hand..

    *Petroleum based lubricants are a no-no..  *Petrol based lubes can and will deteriorate rubber materials.

    🙂👍

    If wet silicone is a worry thay it will pick up and hold dirt there are dry silicone products as well. As far a I know there are sprays that dry quickly. I dont know, however, if the lubricate as well.

    I've used divers silicone for years with no problem at all.

    Ditto. I still have the same jar of Trident that I had from when I had originally purchased my P-rod long ago! I thought about ordering a tube of that SuperLube that Ernest recommends, but decided not too because it's a solution looking for a problem since the stuff I have works :)

    Ditto on pure silicone divers grease. I have been using Trident divers grease on all of my PCP related o-rings (compressor, fill probes, air filter/dryer, etc.) with no issues. Don't overdo the fill probes. Need just a tiny amount to keep them lubricated. Any more than that and they will pick up contaminates.  Here is a link:
