Push-in fittings CQ, for push-fit piping systems
Technical data
Fluid separator CQA
A water separator can be created by
inserting a fluid separator CQA-28
into a push-in connector CQT. The fluid
separator consists of a brass insert
with an O-ring. The short section of
the brass insert is pushed into the
polyamide or aluminium pipe. This
combination is then joined to the
push-in connector CQT.
