Review on PIONEER Air Conditioner Ductless Charging by Aaron Clayton

I bought this to have a wire and gauge kit with me, knowing I would eventually put the Mini in my garage. That summer, a moment came. I used nitrogen cartridges to press on the lines before vacuuming them. It wouldn't stand up to the pressure. All fittings soaped, no leaks found. After reflaring each joint AND still leaking. Soaped the adapter connector. It was an O ring. I had others of the same size so I changed them. When I added more nitrogen to the system a few minutes later, it started leaking again. So I lathered the adapter again and it slowly bubbled up the stewed joint. So I bought another brand (it was less money) and everything worked fine.
