    Valves aren't what they used to be. I heat sink the valves with extra rags...makes brazing a little tougher, but at least I don't cook any more cheap Chinese valves.

    I'd hate to be the guy using a Turbo Torch these day...you have to use them full open and you can't adjust the flame size. Makes for any easy overheat situation.

    I know few guys who can use a Turbo with out over heating line set and valves.

    For what it's worth I personally would not use a pinch off tool on a thru type line. On a process tube or to remove a pressure switch is one thing. Pinching a line then re rounding it is h*ll on the tube wall. That's my

    Great for adding a LL filter without having to pump down system, or if your service valve is broke.
    If you do crimp off area to add a liquid line dryer how do then evacuate the area between the crimped area? Adding a shrader valve?

    just use the low side valve port

    you will have low side valve closed off , so the shrader will still be available to you on the evap side

    you could add a 1/4" tap. Use two pinch offs, cut out old filter and reinstall filter w/ shrader and pull a 5 minute vacuum. reform tube.

    I'm not a fan of pulling vacuum through a TXV.

    Now that I think about it , if you did the pinch off way , your better off adding a shrader near the bad valve , otherwise you wont be able to flow nitro while brazing. Now you can pull a vac from both sides as well.
