Review on 🌡️ XtremepowerUS AC Manifold Gauge Hose with Quick Coupler for Air Conditioner Freon by Hunter Siemon

I bought the refills a few months before actually taking them out of the box. Looks great, didn't fit my car. So I put them on a known good car and the sensors didn't move when the car was off or running with the AC on. Absolutely no movement. REWORK: Upon further investigation, I found that the red and blue hoses were fitted backwards. The side of the valve needs to go into the couplers that connect to your machine, if you don't the valve will never open. After swapping the hoses, everything worked great. My only issue is that the yellow hose appears to have a check valve that prevents contact with the atmosphere unless the valve is depressed. Mines did not have this function. I made a mess of draining my redline after closing the clutch and when the job was done
