    i use the jb 142n pump with 2- 3/8" ports and a 1/4" port built in.

    i use 3/8" to 1/4" yellow jacket hoses and 2 appion core tools on the service ports.

    i dont use a tree, i use the setup that came with the pump, it works just fine, just make sure its leak free.
    I have a Robinaire pump with the 3/8" flare now... Also I have access to a JB 7cfm.... And it is set up just like yours.

    Same setup I use.

    How do you connect your micron gauge to the CRT? With a short hose? I have had problems with the hose collapsing under vacuum and also I suspect it permeates badly. I can't get my Bluvac to hold steady, it always has a slight rise, around .1 micron per second. Never noticed a problem with my Thermal!

    i use the side port on the appion if its possible.

    some units will not let this happen due to tight spots, sometimes i cant get both core removers on.

    worst case i will put the micron gauge on the 1/4" port on the vaccum tree, i like it away from the vaccum, but it will go there before i add another hose to the equation, i try to eliminate all the connections i can.

    Does your Micron gauge have a female fitting or do you use a hose to your crt?

    yes, i use the jb dv22, its female so it screws right onto the valve core.

    i got the blu vac at the top of my list, it looks like it has a male fitting now that i look at it, is that correct?

    if so then u have no option but to use a short vacuum rated hose to connect it.

    Yes, I wish it had a female fitting.

    I'm thinking about using a female to female flare swivel to connect it. That would eliminate the need for a hose.

    surely you could get just a valve that had a swivel on each end? I have no idea where to look but it would be nice.

    JB D10244 Deep vacuum 1/4 sae swivel coupler
    Just picked up two myself, the rubber gasket is smaller then normal though so it looks like it might have to be babied.
    If using for vacuum i reccomend some Nylog on the gaskets.

    This is a Appion core tool that I soldered a 1/4" female QC on.

    You soldered a Quick Coupler onto an Appion Core Tool???? Need a closeup photo of that.
