R-134A





NOTE:
The NSX R-134a receiver/dryer has inch threads, therefore requiring an identification label. The Legend receiver/dryer has metric threads with no label. Do not substitute R-12 parts for R-134a parts.

The desiccant absorbs moisture rapidly, do not remove the plugs from the receiver/dryer until just before replacement, keep the plugs on during disassembly.

Reason for Change
R-134a absorbs more moisture than R-12. The desiccant material was changed to achieve better water absorption capacity. The melting bolt was also eliminated to prevent a total discharge of refrigerant into the atmosphere.
