Description
Unit Dimensions
Diagnostic Couplings are intended to provide facility to access
system pressure for the purpose of pressure measurement.
For transmitting pressure through these couplings to the measuring
devices, no special tools are needed. These couplings can be connected
by hand even at rated pressure.
These couplings are equipped with protective caps to avoid ingress of
foreign particles, when the couplings are not in use. This is also a Safety
device against vibration.
These couplings also can be used for purging air from the system.
Working Pressure 630 bar (9000 PSI) according to ISO 15171-2
Section
For M16 x 2.0 (1620), M16 x 1.5 (1615)
and for special thread at Hose end. ( 1215 )
