Nissan Fairlady/300ZX Z32 Air Conditioning O-Ring Seal (16mm Diameter) Late

Terra Firma Automotive supplies genuine Nissan A/C system components that ensure your Z32 Fairlady or 300ZX maintains factory-correct sealing and optimal cooling performance. This 16mm diameter O-ring seal is the exact OEM replacement engineered for larger refrigerant line connections throughout the air conditioning system on these iconic sports cars. Manufactured from Nissan’s specified high-quality elastomer, it provides superior compression, chemical resistance to refrigerant and PAG oil, and long-term elasticity that prevents leaks under engine bay heat, pressure, and constant vibration.

Z32 owners restoring or servicing their A/C systems understand that degraded O-rings are one of the most common sources of refrigerant leaks, reduced cooling efficiency, and potential compressor damage. Replacing with this authentic 16mm seal restores airtight connections that support strong, consistent cabin cooling for comfortable drives in hot weather or during extended highway runs. Its precise dimensions and material formulation guarantee a perfect fit and reliable seal where generic aftermarket options frequently fall short, making it indispensable for full system rebuilds, R12-to-R134a conversions, or targeted leak repairs.

At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM seals and air conditioning parts that enthusiasts rely on for dependable, long-lasting results. Whether you are refreshing the entire A/C system on your twin-turbo, addressing specific leaks on a naturally aspirated model, or completing a detailed engine bay restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this O-ring upholds the precise engineering standards that define these legendary Nissan sports cars.
