- This kit makes converting a no-brainer! Blue cap is low side, which on most vehicles is the larger line. Red Cap is high side.
- Low side fitting will be aluminum.
Low side fitting - if refrigerant is escaping from (blue) fitting, the fitting is too tight and should be raised up to stop flow of refrigerant.
