Special Service Tool

INFOID:0000000005256827

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.

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.
