    Silicone grease. Good for rubber, electrical connections, etc.

    One would think that they would have changed the whole system to a quick disconnect no rubber involved..

    I asked one our our mechanics about that, and according to him grease won’t break down rubber but spray lubes will.
    Look likes your solution seems to be working. I actually didn’t wind up with 2 seals on each air line tor once when I unhooked yesterday.
     
    ibcalm19 and Wasted Thyme Thank this.

    Interesting. I’ve put hi-temp grease on my glad hand seals and they got mushy. I’ve also bought heater hose and tried it for a oil cooler, and that made a mess and sucked. Maybe it’s just me, and I’m probably wrong. :)
     
    MACK E-6 Thanks this.

    You guys should look into Ballistol. It's good stuff and does not degrade rubber or silicon.

    Glue them in with a couple dabs of 3M weatherstrip adhesive. Black or the old original “gorilla snot” yellow. Any non silicone based grease/oil is gonna eventually eat the rubber. Also oil mixed with compressed air causes condensate. The nasty stuff that needs drained from the reserve tanks.

    Cheap chapstick. A little dab will do it.
