Permanently sealed – independent of the pair of materials
In practice leaks occur again and again in the region of the seal
with screw-fit hydraulic components. The reason for this is that
in the installation of hose pipes connections frequently the
tightening torque is exceeded. With the new
Ecovos fittings from Voswinkel GmbH with
block stop safety the end of installation is
displayed. The difference to the usual sealing
cone fittings here is in the predetermined
space between the two front faces of the
components to be screwed together. This
space prevents over tightening of the
tightening torque and ensures that the
prestressing necessary is achieved in the
screw-threaded pair. This prevents the fitting loosening independently
when placed under a load. Even when loosened and
re-connected repeatedly the full sealing function is achieved.
What is nor the block stop safety holds independent
of the pair of materials. The user does
not need to adjust the tightening torques, for
example when pairing up the hose fitting with
cast-iron or wrought-iron screw connectors.
Ecovos hose fitting is supplied in nominal
diameters of DN06 - DN16 and is expected to be
available from the second quarter of 2016.

66 percent better bending radii
can be achieved. The hose is
available in the nominal
diameters DN19 to DN152. In
addition Dietzel supplies tested
systems, i.e. the integration in all
available nominal diameters
were tested using vacuum,
density and bursting pressure
tests. Integration is possible with
ferrules and hose clamps.
