    New A/C Drier goes POW!

    Working on my A/C system and purchased a new drier for my stock '65 Mustang from a local mustang parts shop. When I removed the plastic cap form the fitting there was loud POW! And pressure that blew out. Scared the Mrs. And she came running downstairs. I don't remember these things being under pressure, if anything should be a vacuum? I am concerned that the drier is faulty? Looks new, but my ears a still ringing.... Should I return it?

    I wonder if it wasn't overcharged with nitrogen.

    It's definitely nitrogen. They are chargeed to prevent moisture from entering the drier before install. It couldn't have been much pressure if it was a plastic cap in spite of the noise.

    Dallas is 430' above sea level. For some reason, I thought the unit was under a vacuum from previous experience. It did shoot the plastic cap across the garage and made my ears ring. The Mrs said it sounded like a bomb went off! I guess the dryer is okay and will keep working...
