    You have to be mindful of what you’re doing. You don’t want to crank your valve all the way open and leave your gauge on. I crack my valve and watch the micron change then I remove the gauges. After it’s removed I open the valves fully. I had the same question when I starting doing it this way. I just watched some videos of Jim Bergman on how he did it.

    According to Joey, the BluVac is impervious to refrigerant and can also take test pressure without damage. Just avoid getting oil on the sensor, because then you will have to clean it.

    Uline sells a great white tape for these lineset - we’ve tried the Polyken and a couple others, but Uline surprisingly has the best we’ve found.

    Looks good. Why not use a proper fitting for the suction service valve? I wouldn’t be surprised if the joint or valve starts to leak. They make 7/8x3/4 reducers or even bushings. Or slide a piece of 3/4 in the 7/8

    The angle wasn’t the greatest there. I make my own fittings, I swedge the 3/4 and swedge the 7/8 it fits well. The real issue is I had the wrong line set. Should of been 3/4 not 7/8. Mistakes happen I’m not worried about it leaking.

    Yea. But you cant make a reducer. The proper thing would to use staybright8 or 45% if you’re brazing over the service valve. You gotta get it super hot for 15% to flow over it. Potential leak from cooking the seals

    Not necessarily l, I take the shrader sand valve caps off, get a wet rag and wrap it tightly around them and use cooling gel . Combine that with knowing how to braze quickly and properly you should have no issue with your seals getting to hot

    I dunno....that pad says otherwise .

    I like to give people a hard time. Makes them do better work.

    All else looks good and i admire you for doing a proper evacuation.

    Are you flowing while brazing?

    You should go far in this career path.

    White gorilla tape.
    I usually slit it on the bottom side and fold it back then just tape and zip tie it back together.
    Same with bends. Just cut it and slide it apart far enough for the benders then slide it back together and tape the joint.
    We use the same tape and ties to hold the bundle together so you don't notice the joints
