Lichamp Car A/C R1234YF R134A Adapters, AC R134 R1234 R 134A 1234YF Quick Couplers Connectors Kit

This is a wonderfully helpful kit. We have 134 and 1234 gauges, but we still have several adapters and injectors and such that are dedicated R134a. We don't cross mix refrigerants, but we do use equipment for 134 on both refrigerants sometimes. Love these.

Works great no leaks

I was planning to give this a one-star review because I couldn’t find clear instructions, and it seems the adapters don’t quite fit the couplers right. You’d need to lift on the engaging coupler part to push the adapter in, but you’ll need a small rubber mallet—I used a 10-pound hammer, which I’m used to working with. Just be careful not to put too much pressure in. Once you’ve pushed the adapters in, the gasket they use moves easier, and connecting and disconnecting becomes smooth afterward. But if you don’t follow my instructions, I promise you’ll want to return them! That said, if you try to do it with your hands, the adapters won’t fit in the couplers, and you’ll want to return it, don’t! Just follow the instructions above. Also, if you’re using these R1234YF adapters on a hybrid AC system, make sure the vehicle is off for at least five minutes to thirty minutes before adapting the low and high pressures. If you don’t, they won’t adapt correctly or fasten correctly!

Once I received them they worked good. The shipment was delayed twice so I got them much later than I expected. The product itself worked fine and was a good price. 4 stars for shipping issues

Ised a dozen times already no issues

High quality, you don’t even need to evacuate the system if you over charge and bleed it. Preferably in Washington or California. Vacuum and gauges your 100% success rate. Stop leak/ dye maybe. Then just chill out man
