Review on 🌡️ FJC Inc. 6025 Quick Coupler Manifold Gauge Set Conversion Kit: Optimize Refrigeration System Performance by Kevin Hutchison

I'm just commenting on the small adapter that comes with the quick disconnects but I'll appreciate them when I get to use them. For years I used my R-12 can stopcocks on R-134 cans by screwing the R-12 collar upside down onto the threaded hole in the R-134 can. The tap then screws into the remaining threads inside the collar and I can use my old AC pickups on my vintage Mustang. The last time I tried this I didn't have enough faucet connection on the freon tank and I ended up pouring out the entire contents of the tank to charge my air conditioner. The FJC adapter screws right into the R-134's outlet and I can use my gauges with ease. Oooh! Get one. You will not regret it.
