    What happened ?
    They went out of calibration, couldn't even be zeroed. I shipped them to Doug Lockhart so he could look them over. He cut his finger on one of them and promptly smashed them with a sledge hammer. It's a long story.

    I use them ALL the time. Whenever I'm doing maintenance I use those first, and then I'll whip out the digital's if I need to. I use BV on mine and also carry around a 6" hose incase I need to get in a tight space....perfect example being the retarded way Rheem installs their valves on some ODU's. I'm thinkin about getting another set and calibrate that for a different common reefer just to have them. United Reefer should have everything you need to rig this up, at least the one over my way does.

    I'm confused..... I've been using a guage set up like this for over 15 yrs....... I use it to check seal pressures, and to verify transducer readings on chillers........ am I missing something special about the one in the picture that was posted?

    Thanks guys.

    I got the YJs from HVCRtools.

    The advice on using a the ball valve hose was a great suggestion.

    Doesn't sound like too long of a story!!!

    I have a set of these and I find them very useful for all the reasons everyone uses them for....

    I use mine mostly to verify proper compressor phasing at start up.

    LOL! Well the "rest of the story" is long. Let's just say that Doug isn't very fond of Ritchie Engineering Company, Inc.

    I use one and it is true that you can have clearance issues. And sometimes it is the unit's fault. On some models, you have the schraeder on the back side of the service valve and it doesn't fit because of other factory stuff in the way. They are not flexible at all. In these cases, I have one of those really short hose extensions with a built-in ball valve that is meant to go on the end of a regular hose. It has a male end and a female end and takes care of the problem. If you make one, just find a fitting to attach the gauge thread to that hose extension thread because you will have clearance issues with the other setup.
