    Service ports

    Will try to post pics later. Was working on a Carrier chiller and could not find a service port. Found it had these big automotive looking things. Has anyone seen these and can you still get adapters for it. Was told it was something they tried that never took.

    Thats the one. I had a hard time getting them from my local carrier rep, the people there are too dumb I guess.

    I was able to get United to order them for me. Took a couple weeks to get.

    Awesome, thanks. Will see where to get them. Any upside to these ports?
    Was told better flow but I have no experience. Hard to believe after 32 yrs I just came across this. The guy who normally takes care of this account moved and when I told the office there were no ports they thought I was crazy.

    The only real upside is that they prevent most people from messing with the units charge. It takes too much effort to get the port adaptors for most hacks, so they move on to the next victim.

    I beleive the name of the valve is Coremax. JB Industries makes an adaptor/core removal tool. My local RSD stocks them. I think it's about $100 which is about $300 less than the ones from Carrier.

    No, its not a coremax. This is a larger version of a automotive type port.

    The coremax ports use the same 1/4 flare hose service connection as a standard port.

    Thanks for the link. Tried to find them but had no clue what they were called.
    Carrier couplings. Go figure. I see they are 3/8 flare.
