11.12 fitting the push-fit connectors
!
Material losses
Tighten the screw cap of the push-fit connector by hand.
Never use a tool.
The push-fit connectors are equipped with a retainer with stain-
less steel serrations and an O-ring for sealing. In addition, they
are equipped with the "twist and lock" function. Simply turning
the screw cap by hand will secure the pipe in the connector and
push the O-ring against the pipe to seal it.
!
Material losses
Support sleeves are required when using plastic pipes.
Making the connection
The connector must be in its relaxed position before the pipe is
inserted. In this position, there is a small gap between the screw
cap and connector body.
