Joywayus Connectors Adapters Couplers Conditioning Review

I was hesitant at first to purchase Joywayus connectors adapters couplers conditioning because of its high price, but boy was it worth it! Thanks to my knowledge gained in practice as an automotive technician, I found this tool to be top-notch in terms of performance and efficiency. It connected flawlessly to all models of AC units, and the fact that it is made of durable materials guarantees its longevity. The only downside I found is that it may not be the best choice for DIY enthusiasts who…

None of them worked. The red top valve worked in reverse and the blue bottom valve didn't open at all. I had to go back. Garbage.

I think I bought these as a 'lucky accident' my R-134a set and thought they would be threaded onto hose ends. Different threads but not lost all because I can use them with my old R-12 set. no need" and they would be right except if someone switched back to R-12 and had R-134a fittings, pressure difference between them and with R-410. So now I don't have to unplug R-134a adapter fittings to get R- $12 to check 12 or R-410 etc. It took me more gas to get them back.
