Series 5000 quick-release couplings
Series 5000 quick-release couplings
are suitable in situations where, for
plant engineering or safety reasons, the
connection or disconnection of tubing
must be repeated several times. These
operations can be performed with
no need to release the pressure and
therefore a considerable amount of time
can be saved.
Series 5000 quick-release couplings
with mini-profile DN 5 are compatible
with couplings Rectus Series 21 - 90,
Legris 21.
Series 5000 quick-release couplings with
European profile DN 7 are compatible
with couplings Cejn Series 320.
