Review on 🔧 LICHAMP AC R1234YF R134A Gauge Set: Efficient Automotive 4 Valve Manifold Gauge for R1234YF and R134A Refrigerants by Dean Pinheiro

I returned it. I wanted to use it to refill my 2018 civilian car with paint. I blasted the line to the point where the blue coupler met the blue hose and when I started to fill up my car I couldn't see the coolant flowing through the sight glass, the blue gauge showed pressure. The air conditioning in the car was switched on for 15 minutes, nothing. I think the pusher in the clutch is not long enough to open the car's valve. It was like pumping up a tire.
