HOSE ASSEMBLIES
Installation
1. Check sizes and quantity of hose assemblies as shown on submittal drawing.
2. Connect all hose assemblies to the appropriate equipment as shown on submittal drawing. Provide and
install necessary plumbing fittings to present a neat appearance and to ensure that hose assemblies do
not touch floor.
3. To ensure proper installation and minimal wear of hoses, follow the examples shown below:
Do not offset
couplings, this
creates torsional
twisting and undue
strain causing
premature failure.
Allowing a sharp
bend strains and
twists the metal
hose to a point of
early failure at the
coupling.
Closing in the
diameter at the
coupling creates
double bends
causing work
fatigue failure of the
fittings.
Couplings and hose
should be installed in
the same plane as
shown.
This is the correct way
to install metal hose
for vertical traverse.
Note the single natural
loop.
Maintain the minimum
or larger bending
diameter between the
couplings for longest
life.
