Review on LemonBest Car AC Converter Hose Kit: Effortless R134A R12 Refrigerant Converting Adapter for Efficient Air Conditioning by Rudy Santos

Here's what I have in my kit: Blue 1/4" M to 7/16" SAE F hose adapter with valve core and swivel joint. Used for R12 connection at the bottom. Red 1/4" male to 3/8" SAE F hose adapter with valve core but no swivel. Used for R12 high side connector. (In this case, the seal in the shaft looks a bit deformed). R12 Adapter Low.90 degrees 1/4" AG to 3/8" SAE IG. With valve pusher. p12 hello. Some older cars had the same fitment on both the low and high side, so having two adapters helps. 90 degree adapter from 1/4" AG to 1/4" IG. With valve pusher. 90 degrees is suitable for accessing ports where there is not much space. Straight adapter 1/4" AG to 1/8" NPT AG. With valve insert. Can potentially be used on a gauge manifold. Straight adapter 1/4 inch M to metric 9x1 mm M. With valve insert. I don't know what it's used for. female fitting too small for 1/2" ACME, seems to be loose on 1/4" flare. Has a valve depressor. All in all, a decent set for the price.
