compressor label before adding refrigerant oil to A/C compressor/system. See Fig. 2 . The following R-134a refrigerant oils are currently available. Lexus PAG Refrigerant Oil (ND-OIL 8) with 10P/10PA swashplate (piston) compressor. Synthetic Refrigerant Oil (ND-OIL 9) with through-vane Mercedes-Benz PAG Refrigerant Oil (001 989 08 03). Nissan PAG Refrigerant Oil (KLH00-PAGR0) with rotary vane compressor. PAG Refrigerant Oil (KLH00-PAGS0) with piston (swashplate) Saab PAG Refrigerant Oil (40 74 787). SERVICE EQUIPMENT Because R-134a is not interchangeable with R-12, separate sets of hoses, manifold gauge set and recovery/recycling equipment are required to All equipment used to service systems using R-134a must meet SAE standard J1991. The service hoses on the manifold gauge set must have For identification purposes, R-134a service hoses must have a Black stripe along its length and be clearly labeled SAE J2196/R-134a. The low R-134a manifold gauge sets can be identified by one or all of the following. Labeled FOR USE WITH R-134a on set Labeled HFC-134 or R-134a on gauge face Light Blue color on gauge face In addition, pressure/temperature scales on R-134a gauge sets are different from R-12 manifold gauge sets. SYSTEM SERVICE VALVES SCHRADER-TYPE VALVES Schrader valve is similar in construction and operation to a tire valve. When a test gauge hose with built-in valve core depressor is attached, If test hose does not have a built-in core depressor, an adapter must be used. Never attach hose or adapter to Schrader valve unless it is first Refrigerant R-12 Schrader-type valve cores have TV5 thread size. Refrigerant R-134a Schrader-type valve cores use M6 (Metric) threads. R- Fig. 1 . SERVICE VALVE LOCATIONS SERVICE VALVE LOCATIONS NOTE: Synthetic/PAG oils absorb moisture very rapidly, 2.3-5.6% by weight, as compared to a mineral oil NOTE: Refrigerant R-12 service hoses will ONLY be labeled SAE J2196. NOTE: Although similar in construction and operation to a tire valve, NEVER replace a Schrader-type valve Vehicle High Low Audi (14)
