This product came to me cut open, taped over, and the thread tape has groves in it from being screwed into a manifold and then removed. Definitely not new. Very disappointed

I use them for my quick connects, nothing worse than not being confident in your gauges P/T checking superheat subcool. Has adjustment for zero calibration.

As far as analog gauges go, these Yellow Jacket Glycerin filled gauges have no equal. Before upgrading the gauges on my manifold to these, I had Yellow Jacket regular 3-1/2" Flutterless gauges on a yellow jacket heat, and almost every day they would come off "0" requiring adjustment every time i went to use them I bought the rubber condoms for them and it helped slightly but i would still have to zero them almost once a day. I've had these liquid filled gauges high and low side, have yet to have make any adjustments. As a service technician, accuracy is essential, if your gauge is just a few degrees off, well then your super heat or sub cooling readings are always a few degrees off, which doesn't sound like a big deal... but it is in regard to a refrigeration system, especially with R-410a. I would buy these again, and probably will when its time to give my manifolds a face lift again.

So far very happy with gauge. I get steady readings the it's very clear so I can see to read even with bad eye sight.
