New OEM pressure release valve that screws onto the high-pressure AC line right where it attaches to the compressor.

Applicable to all Z32's fitted with R134a systems from the factory (94+ models).

The pressure release valve for R12 cars is no longer available from Nissan.

Although there are some differences and it isn't exactly the correct part, we have used this R134 AC pressure relief valve on earlier model Z32s fitted with R12 systems for quite some time with no problems.
