REFRI GERAN T LI N E COU PLER
DESCRIPTION
A spr ing-lock type refriger ant line coupler is used
to connect the front sect ion of th e un der body dis-
charge line to the compressor section of the discha rge
lin e. A secondar y reta ining clip may be installed over
the con nected coupler for added prot ection .
The spring-lock r efrigera nt line coupler requires a
special disconn ect tool for disen gaging th e two cou-
pler halves.
OPERATION
The spr ing-lock coupler is held togeth er by a garter
spring inside a circular cage on t he male half of th e
fitting (Fig. 37). When t he two coupler halves a re
connect ed, the fla red end of the fema le fitt ing slips
behind th e garter spring inside th e cage on t he male
fitting. The gart er sprin g an d ca ge prevent the flared
end of the fem ale fitting from pulling out of the
cage.
