Raider V6-3.7L SOHC (2006)
Hose/Line HVAC: Description and Operation
Coupler - Refrigerant Line
COUPLER - REFRIGERANT LINE
DESCRIPTION
Spring-lock type refrigerant line couplers are used to connect the A/C accumulator and the A/C liquid line to the A/C evaporator. Secondary retaining
clips are installed over the connected couplers for added protection.
The spring-lock refrigerant line couplers require A/C Line Disconnect Tools 7193 for disengaging the two coupler halves.
OPERATION
The spring-lock type refrigerant line coupler is held together by a garter spring (6) inside a circular cage (7) on the male half of the fitting (1). When the
two coupler halves are connected, the flared end of the female fitting (2) slips behind the garter spring inside the cage on the male fitting. The garter
spring and cage prevent the flared end of the female fitting from pulling out of the cage. Some applications use a connection indicator ring (4) to help
indicate when the two coupler halves are fully connected.
Two O-rings (8) are used to seal the coupler connections. These O-rings are compatible with R-134a refrigerant and must be replaced with O-rings made
of the same material.
A secondary retaining clip (3) is installed over the connected coupler (5) for added protection.
