FIGURE 1 - A/C REFRIGERANT ACCESS FITTING
Some vehicles may exhibit a condition of inoperative or poor A/C performance. This condition may be caused by a loose or missing cap and seat
assembly, which results in the loss of a significant amount of refrigerant through the valve core located in the access fitting.
Air conditioning High side and Low side access fittings are supplied with a black plastic cap and seal assembly which provides the primary refrigerant
seal for the service fittings.
When servicing or leak checking any vehicle's A/C system, make sure all access fining cap seals are in place and tight. Refer to Figure 1. Caps should be
threaded on until contact with the O-ring seal is made and then tightened another 1/4 - 1/2 turn to ensure proper sealing.
