Just curious; just noticed with a newly purchased accumulator that one of the caps was off and must of come off during shipment. Should I be concerned with moisture being absorbed by the desiccant material ? I would think that the desiccant would not of gotten saturated with moisture but just wanted to check and be on the safe side before I completed the install. Thanks.
You will be fine.
I encountered the same thing. Why will he be fine? Air usually is at 50% humidity or higher. Since the box isn't sealed, there's an unlimited amount of moisture present. He also doesn't know how long the cap had been off.
The likely reason the sales rep would cap it on the way to the counter would be to lie. Why would they open the package? I'm hoping most people are moral enough not to do such a thing. There are posts here that say that the desiccant cannot be dried. Since no one seems to know, I'm going to play it safe. I went back, and picked up the replacement accumulator. This one had red caps on it and looked very clean (the first one had black caps). I'm glad the sales rep at the NAPA autoparts store didn't just give me back the one I returned. And I should have put a mark on the first accumulator so that I could tell for sure, but this one definitely looked different.
And why would it matter if the sprinklers went off or if moisture from the air got into the can? Since we do not know how long the cap was off, it wouldn't matter. It could have fallen off 10 years ago. My accumulator was made in May of 2001.

The ones i have bought usually are under a vacuum, and hiss when you pull the plugs. So thad be a good indicator.
1990 Pontiac Turbo Grand Prix
1990 Pontiac 6000 LE V6
Both have R12 A/C
It says here that pulling a vacuum won't dry it. I think cap-off = defective.
