Refrigerant Line Coupler

A/C Condenser - 2.4L Turbo Engine:

On vehicles equipped with the 2.4L Turbo engine, a spring-lock type refrigerant line coupler is used to connect the liquid line to the A/C condenser. A secondary retaining clip is installed over the connected coupler for added protection.

The spring-lock refrigerant line coupler requires a special disconnect tool for disengaging the two coupler halves.

Spring - Lock Coupler - Typical:

The spring-lock coupler is held together by a garter spring inside a circular cage on the male half of the fitting. When the two coupler halves are connected, the flared end of the female fitting 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.

Two O-rings on the male half of the fitting are used to seal the connection. These O-rings are compatible with R-134a refrigerant and must be replaced with O-rings made of the same material.

Secondary clips are installed over the two connected coupler halves at the factory for added blow off protection. In addition, some models have a plastic ring that is used at the factory as a visual indicator to confirm that these couplers are connected. After the coupler is connected, the plastic indicator ring is no longer needed; however, it will remain on the refrigerant line near the coupler cage.
