    took ball valves off hoses so there were to core depressors in any hoses
    Pulled cores out, took about 10 minutes to pull down to 500, about 15 to pull down to 280, closed ball valves on core tools, killed pump and let sit for 20 minutes. And 570 is what i got. installed cores, pulled vacuum down again, let urr rip. Good enough for me!

    It suprised me how good it worked, saved a bunch of time, If anybody makes one make sure you raise or lower the tee a little bit, when i made this one i didnt think about it being so close to the handle of the pump. other than that worked great! I usually put it in a vacuum and pick up all my stuff and put everything back together, now my vacuum is done before i finish picking up

    I like it. Every fitting and 'seal' you can eliminate will always help.

    This is on my list of things to do when I get back in the office on Wednesday.

    I already measured mine out so the handle isn't an issue!

    Good work! Definitely giving this one a try considering the lengthy time it seems to take pulling a vacuum on some 410a systems.
