R-12 to R-134a high side adapter. This adapter will convert the R-12 charge to port to accept R-134a gauges. The adapter is for the larger size port, please check your port prior to ordering. To check the ports unscrew the cap from the low side port and try it on the high side port. If the low side cap fits the port this is the correct part for your vehicle. If it does not fit you will need part number V331.
This adapter includes a new valve core. The old valve will have to be removed prior to installing this port.
