    Anyone have a leak down tester to pressure test saws with, that they would want to sell,?? Looked on eBay ouch!

    This seems like such a random tool I will never find it on CL or similar!

    Good tip!! You can even get those as loaners at auto parts stores . How long should it hold a vacume ? Forever?
  4. Here's what I use

    Just a gauge and some tubing

    And to pull a vacuum or to pressurize I use this. I put a quick connect on the inlet and outlet so its simple to switch back and forth.

    Just what I had hanging around.

    Ideally, yes, but that ain't happenin'.

    Generally holding .5 bar (roughly 7 psi) of pressure and vacuum (test both ways!) for 30 seconds is acceptable.
