[Solved] Do quad orings melt?

out of all of them i could see that one being the easiest to melt(other than the level 10 bumper) since it appears to be buna esque.

Never saw one melt. They get hard when they get old. I use Viton as they tend to hold up better. What kind of oil did you use in that gun?

if seen tons that stick to the on/off pins in a melted goooooo.

Autolube from AGD. I'm going to throw another oring in and put the gun in the car and do some tests tomorrow. I'm wondering how hot it got in my trunk to see if that is the possibility.

I took 3 valves and all of them had the same issue. I'm 99% sure that it was the heat from my trunk since all of the valves were working last week at my home field. I put some new quad orings in and everything returned back to normal. For any traveling e-mag people, remember to store your valves in a cool place.

They were probably old to begin with and the heat did not help the situation.

Florida garages are terrible on them ,, I kept them in my box and changed them regularly , that stuff is like tar

Yes AGD quad orings will deform under extreme heat. Not exactly sure what the specific amount of heat is, but it seems to be attainable in a hot car...
I've seen many deformed and melted in the on/offs just like Bunny has. Also seen them become deformed in storage due to heat.
They seem to be much more susceptible than the nitrile buna or cast urethane.
Unfortunately I don't have the specific temp specs on our quads. I just did a quick search and cars can reach 172 degrees inside if temps reach 100 degrees outside.
Obviously the quads are melting somewhere above 100 degrees and below 172 degrees.

Not to mention how a lubricant might interact...
