HFC134a INFORMATION
Because of the significant chemical differences between R-12 and HFC134a refrigerant, many A/C system components have been revised.
O-RINGS:
HFC134a system O-rings are manufactured from an entirely new material. In addition, sealing surfaces have been redesigned thereby requiring the
HFC134a O-rings to be slightly thicker than the equivalent R-12 O-ring:
^
0.4 mm thicker for liquid tubes.
^
0.6 mm thicker for discharge and suction tubes & hoses.
OIL:
HFC134a systems utilize polyalkylene glycol (PAG), a synthetic lubricant in place of the mineral oil used in R-12 systems, which is identified as ND-Oil
8. PAG type lubricants have a significantly higher moisture absorption rate than the mineral oils currently used in Toyota R-12 systems.
In general, PAG oil can be stored in a cool, dry place for up to two years if it has not received excessive exposure to the atmosphere. It is necessary to
properly seal the ND-Oil 8 container immediately after each use. If ND-Oil 8 is left exposed to the atmosphere for more than 24 hours, it MUST be
discarded. Proper disposal procedure for oil should always be used.
Take care not to spill or pour any ND-Oil 8 onto a vehicle's body or any painted surface. If this should occur, wipe the surface immediately with a soft
cloth.
