Glad hand seals sticking together.

Try putting the grommets in backwards. With the thinner, wider part of the flange on the inside of the hole. It takes a bit of fannagling, but you should still get a good seal and they may stay in better.
I have tried this a few times and it seems to work...

 

I actually looked in the parts room to see which manufacturer it was because we have been having this happen a lot lately. Now I forget which one it was. Going to look again on Monday. Never had this happen before Over the years.

 

Lubriplate.

 

A very small amount of grease will solve your problem.

 

it is my experience that spit or any kind of moisture is what makes them stick together.

 

Talc

 

I have that happen , never had it before, most of the time they won't fall out of the glad hand. Chinese are not very good at making glad hands , never had them break, now they break

 

in all my years, i ain't never had that happen.

best i can suggest is a light spray coating of maybe PAM cooking spray, as oils, lubes maybe eat away the rubber.
