Review on Boltigen Coupler,R1234YF Charging Connector Air Conditioning by Ronald Bleimeyer

Revainrating 5 out of 5

Excellent adapter: Air conditioning tools and equipment

Excellent adapter. Allows working on new r1234 systems with r134 hardware. In my case I needed to replace the AC condenser so I switched back to r134 instead of the much more expensive r1234 refrigerant. R 134 is compatible with newer 1234 oils so there are no shifting issues. There is also no need to change the hole.

Pros
  • Air conditioning tools and equipment
Cons
  • Small parts
