Boltigen R1234YF Low Side Quick Coupler，R1234YF to R134A AC Charging Hose Adapter Fitting Connector for Car Air-Conditioning

Very good

Works as it should

This was perfect for my Impala. For whatever dumb reason Chevy decided to make getting to the a/c input very difficult. And when I did get to it it was all most impossible to get the hose on to refill because it is mounted horizontally under some hoses. My mechanic told me about this. I found it. Got it. He put it on and now I don't need to call him for that problem. Well worth the cost which was minimal to me

Lo compré ayer llegó hoy y lo utilice de inmediato y como lo esperaba pude ponerle líquido a mi carro ya que tenía la manguera R-134a y no quedaba por ser más pequeña y busqué en Amazon y encontré este adaptador cabe recalcar que cambié la manguera del AC y estaba vacío dicen que no no es bueno Mesclar ambos refrigerantes pero yo aquí lo llene desde cero con el 134 y funciona al máximo

It work pretty good not bad for the price had to kinda hold it in one place as I was filling the air-conditioning with it , but it worked thanks

Great adapter. Allows working on new r1234 systems with r134 equipment. In my case I had to change the ac condenser so I am converting backwards to r134 instead of the much more expensive r1234 refrigerant R 134 is compatible with the newer 1234 oils so no problems making the switch. No need for orifice changes either.

This is a must have if you’re going to charge your ac in vehicle. No parts store in my area carried anything like this. This little part saved me lots money, by not going to a dealership.

Worked as stated Thanks
