Johnsen’s R-134a A/C Refrigerant 12-pack/12oz cans

Keep your car’s air conditioneer cool all summer long with R-134a. This product is for use in retrofitted and or factory installed R134a auto air conditioning units. Our product is 100% Pure National Refrigerants R134a. There are no Gimmicks or Additives Our Refrigerant is proudly filled in the USA. Over time, the seals and connections in your vehicle’s air conditioning system can allow a small amount of R-134a refrigerant to leak past and escape into the atmosphere. During cold weather in particular, the rubber seals shrink and provide a less secure seal. Adding R-134a refrigerant to replace the leaked refrigerant can be done at home by the average do-it-yourself mechanic for a fraction of the cost of paying an auto repair shop to perform the procedure. Other than the tools needed to charge your A/C system normally with, like a pen, safety glasses, gloves, there are no special tools required for the new self-sealing valve system. This product contains 12/12oz cans
