The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.
HFC-134a (R-134a) Service Tool and Equipment
INFOID:0000000005256828
Never mix HFC-134a (R-134a) refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.

Component
INFOID:0000000005256830
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at or
around the connection.
