I bought 4 used perlick secondary regulators awhile back. Building the keezer finally but just started testing these regulators to find out there is a leak. Read everything and can't figure this out. When individually hooked up to my primary co2 each individual regulator holds pressure even if isolated from gas source for hours. Once connected in series there is a slow leak definitely not from the series connection hex nipples though. How is this possible? I'm stumped.
