The AD-51 and AD-65 Dedicated Conversion Adapters both have an R134a or R1234yf port as the male end: the AD-51 has a 1/4 SAE female end and an R134a male end, and the AD-65 has a 3/8 SAE-LH female end and an R1234yf male end.
Product Advantages
1. The AD-51 converts a 1/4 SAE female end to an R134a port, and the AD-65 converts a 3/8 SAE-LH female end to an R1234yf port.
2. The AD-65 uses an LH left-hand thread that matches the R1234yf port specification, avoiding mix-ups with R134a.
3. Other thread specifications can be customized to ISO, UNC/UNF, and NPT standards.
Applicable Scenarios
Suitable for repair shops that need to connect hoses and equipment between R134a and R1234yf vehicles, as a practical adapter during the refrigerant generation transition.
We can design and develop according to the needs of our customers to meet the requirements of different clients.
