    I use them and sometimes I wonder just how "tight" they actually are. I was impressed on just how sensitive the micron gauge really is. A power cap leaking over one hundred feet away shows up quickly. Since it's not sensing pressure it really amazes me.

    Thats great I'm getting one. I smashed my piece of crap supco VG that I have only owned for 6 months into a hundred little pieces today. I went to use it and all it would show was 0, new battery, 0. Supco makes crap as far as I'm concerned.

    here is something I Bend posted a while back.

    http://hvac-talk.com/vbb/showthread....ghlight=vacuum

    not the exact process that i do, nor the hoses i use. looks as though he is using 1/4 hoses. i use 3/8's in hoses that have the 3/8's connection on one side to connect to the vacuum tree and a 1/4" on the end with a 45° angle and these are the black vacuum hoses that yellow jakcet makes for this application.

    yellow jacket part # 93866 is a complete kit, two 4ft hoses, the 2 valve vacuum tree, and two quarter trun ball valves kit can be found in the 200-250 price range

    and part # 93876 adds the vacuum gauge that we are talking about to the above i dunno how much that kit is

    most vacuum gauges don't sense pressure. is that what your saying is not sensing pressure

    the all use a thermistor

    the pix that is posted need one more part...a shut off right before the micron gage. This would eliminate the chance of having a pressur3e hit the micron gage while charging. This is the set up I use. Iplace a charge into the tree by using the tree shut offs. When I get a positive pressure in the system, I switch to a ste of gages and complete the charge.

    Its absolute pressure i believe, but you can see that you have a problem.

    That pic in your last post is the same gauge I have

    just take it off before you charge...

    none of those pics are mine. they are from others on this site. his vauum gauge is still in the system if he closes the ball valves, so then he could see a rise in microns

    since i do alot of heat pump work, i put my micron gauge on a common suction port. it is best to get the vacuum gauge as far from the pump as you can. but text book doesn't always work in the field

    and when i am done with a vacuum, i close the ball valves, remove the black hoses, connect my gauges and open everything up and add the charge.

    since i use Y/J low loss fittings and leave refrigerant in my gauges all the time, i know they are dry and ready to go

    or you can remove the vacuum hoses, and put on a set of regular hoses and purge each hose before opening the ball valve
