    I will put up a "build your own vacuum kit" for the parts. I am guessing there are a few techs who have most/some of the parts that would just like to purchase the pieces they need to make a complete kit.

    That would be awesome, Jim. Judging by all the talk on here, I'm sure MANY techs have the hoses and CRT's

    I like to bleed/purge the CRT a bit before installing the core too......the air trapped as you're screwing on the end of the CRT (between the ball valve and end cap) is probably more than you can introduce removing the vac. gauge while the system is in a vacuum.

    cool setup! thanks for taking the time!

Typically on larger systems you can also connect at the receiver, discharge line, suction service port and possibly other places.
    here's my tree setup. allows flexibility for number of ports. double flare fitting connects directly to Robinair port. then add T or four way male flare fitting.

    I guess what I meant by tree was the Yellow Jacket or a fitting directly off the vac pump, just trying to eliminate possible leak points.

    Thanks

    Per the few requests, I rebuild the kit as an option kit.

    CV,
    It would help to polish those fittings ends as far as a good vacuum seal. You might also try to assemble it with some Nylog.

    I had a collection of parts like that also I carried for years.

    Typically, I don't like these kind of video's but you did a good job. I don't like the flexable tree but that's my taste. I have two solid multi-tap trees that I can use off of my vacuum pump.

    I try to find or create a third tap point for connecting my vacuum gauge as far away from the vacuum pump as possible just as a security blanket for me.

    Good video, good instructions and good equipment......but everything is just too clean including you. Next video roll in some mud or something so you will look more like us!

    Thanks

    I am glad you like the video, It was not intended to be one of "Those types of videos" I not only co-own TruTech, but I am also a full time instructor at Cuyahoga Valley Career Center in Brecksville. I spend a lot of time on TruTech Tools trying to make it as much of a training resource as a place to buy tools. A lot of technicians have the same problems when it comes to evacuation.

    1) The amount of time it takes
    2) Managing leaks
    3) Getting consistent results
    4) Understanding how to use a micron gauge and what it tells you


    The "flexible tree eliminates a lot of mechanical connections and a ball valve that are typically in a vacuum tree. I have a simple brass tree and it has 6 potential leak points. Using a brass tee and a hose knocks it down to three.

    I agree with you on having the micron gauge as far from the pump as possible when you are able to do that. On a typical residential system though there are only two service ports making the core tool the ideal place to make the connection. When the core tools are closed and the hoses isolated, you now only are reading vacuum on the line set an the evaporator coil. The brass connection between the micron gauge and the core tool is not gas permeable so the system should stabilize in a few minutes to get an accurate indication of vacuum.

    I will consider getting dirtier, it took me the last 10 years as in instructor to get most of it off.

Using a brass tee and a hose knocks it down to three. What about just a fitting right on the pump, MPT x flare x flare. Would't that be the best?

    Yes it would be but I've gotten a lot of resistance about removing that fitting from the pump. They are in tight and some are afraid they will crack fittings. This is a nice bolt on solution.

    thanks for recommending Nylog.. that's some neat looking stuff
