Where is the low pressure service port?
The can i looked at today was really confusing, it had a built in gauge on it and everything it was a huge can for 20 bucks and says its reusable. My questions are where is the low presure service port that it says to add this to?
Also? it says that the can can explode in my hand or become a projectile. How do i lessin my chances of this happening?
How do i know for sure that my a/c only needs charging?
This sounds a little dangerous, or does the manufactuere just over rate the risk for liability reasons?
