Spring-lock Coupling
• Spring-lock coupling is used for pipe-to-pipe connections. As a result, pipes can be
connected easily, maintenance of torque is unnecessary, and serviceability is
improved.
• There is a garter spring in the cage on the male side (cooler pipe or cooler hose
(LO)) of spring-lock coupling type and the end of the pipe on the female side (A/C
unit) is flared. When the pipes are being connected, the flared end of the female
side forces the garter spring on the female side to expand, and by fully inserting the
male side into the female side, the flared end is locked by the garter spring. When
the cooler pipe or cooler hose (LO) is replaced, the additional indicator ring comes
out after connecting; indicating that the flared end is locked.
