The stuff has to leak out!!!!
Let's look a a regrigerator. If what you say is true, then we'd all be having our refrigerators recharged every few years. They don't leak because they're a nearly sealed system. Nowhere to leak out, no shakin and rattling down bumpy roads like a car.
The 25 psi you were reading was on the low side of the system. The high side can reach 250 psi. Those numbers change with charge amount.
Just more info to consider.
