Installation of Flexible Hose Assemblies
In general hose assemblies should be handled with care to
prevent excessive bending, twisting and kinking since this
reduces the life of the hose assembly considerably. Particular
attention must be given to preclude hoses from wear, snagging,
kinking, bending smaller that minimum bend radius and
cutting, any of which can cause premature hose failure. Large
diameter hoses and very short hose assemblies are more
prone to kinking. Special care must be taken to prevent
twisting of hose assemblies that do not incorporate assembly
fittings with spanner flats to counteract while the nut is
turned to the connection fitting (e.g. Parker/Statoflex PTFE
hose type 101). Twisting of the hose can be determined from
the identification markings running along its length.
The flexible hose should be installed so that it will be subject
to a minimum of flexing during operation.
Installation of PA Hose Axial Plug
1 Install the plug-in screw into the fitting (e.g. firewall, brake).
2 Simply insert the axial plug into the the plug-in screw until
it is snapped as outlined in Figure 2.
Removal of PA Hose Axial Plug
1 Screw out the plug-in screw together with the snapped axial
plug (see Figure 2).
2 Disconnect the plug-in screw from the axial plug by insert-
ing a sleeve (7 x 30 x 0.5 mm) as outlined in Figure 2.
