Review on Yellow Jacket 49887 Titan 2-Valve Test and Charging Manifold Fahrenheit, Pressure Scale, R-22/134A/404A Refrigerant, Red/Blue Gauges by Scott Gafur

I had an old set of old type 4 square valves. I used them for about a week and they were leaking. They turned around and sold a set of gauges for $350 after I rebuilt all the valves for $75, waited for scale, 4 years saw them and decided I would give them another chance but a week later I pulled this vacuum, it wouldn't work. t pulls below 970 microns, changed sensors and within 39 minutes it dropped to 640 so tell me! @YELLOW JACKET they need to step up I've had the same sensors for 25 years and no problems
