My mechanic just told me that I had a leak in the AC line and that he had to replace my o ring with the closest fit he had. He says that it eliminated the leak he discovered there. he's concerned whether the o ring he used will hold. I don't know the clearances involved but I'm assuming it's a pretty high pressure. Can he rely on his fix or must he use the manufacturer's recommended item?

It's for a 2000 Honda Accord 4 DR LX. Btw, is this type of an item have a lifetime warranty?
