When the summer sun reminds you that your air conditioning could use an overhaul, the first step is to make sure that it is sealed properly. There are O rings at almost all pipe connections and if they are worn out and dry-rotted, your vehicle will not be able to hold the refrigerant in. Replace all of your O-rings and be sure that that expensive refrigerant does not escape out.
Designed just like the original units, these O-rings will slip on and keep all of that pressure inside the system. Complete kit for your vehicle.
