Installation and Reassembly Guide SSB 16 SS
Safety Swivel Break "SSB 16 SS"
for AdBlue / DEF (Diesel Exhaust Fluid) Urea Solution
Zapfventil
(ZVA Slimline AdBlue)
SSB 16 SS is a self-sealing reusable break-away coupling designed to protect dispenser, hose assembly and car
against damage which can occur by drive-off incidents. As a nozzle break it is directly fitted to the ZVA Slimline
AdBlue (DEF) nozzle. Before delivery each SSB 16 SS is tested regarding the break-off force and tightness under
pressure (5.25 bar acc.to standard EN 13617-2). This is documented by the factory date code. When a pull
between 80 kg (800 N) and 150 kg (1500 N) is applied, either axially or at an angle as quite often occurs in practice,
the coupling separates.
WARNING : Before installation determine if the construction of the dispenser and the pull resistance of the hose
is suitable for a pull force higher than the maximum separation force, in all driveaway directions.
INSTALLATION INSTRUCTIONS
Switch off pump. Release pressure in hose
G
Remove nozzle from hose assembly and drain hose
G
Remove existing swivel from nozzle
G
Push break sleeve BS 16 back over the hose
G
assembly and anti-kinking sleeve KS 16
Screw SSB 16 SS with assembled strainer into
G
nozzle
Screw SSB 16 SS onto the hose assembly
G
Activate pump and check carefully to ensure
G
connections are tight
Push BS 16 over SSB 16 SS until the lip rests in the
G
groove
The break sleeve BS 16 is an integral part of the
SSB 16 SS and helps protect the break-away part
against external damage in the event of a drive-off.
A range of colours is available for product identification.
REASSEMBLY AFTER SEPARATION
NOTE: This work must only be done by an authorised
service engineer who should also test and check the
dispenser, nozzle and hose connections for possible
damage. The whole system is then subjected to a pres-
sur test before being put into operation again.
a) Switch off pump. Release pressure in hose
b) Push break sleeve BS 16 over the hose assembly
and the anti-kinking sleeve KS 16
c) Unscrew SSB body from nozzle and SSB break-
away part from hose

d) Clean all parts (crystalized urea solution can be
washed away with destilled water or urea solution).
Check all parts for damages caused by the accident
like ovalness, other deformations or broken plastic
parts. With such damage, the safety break coupling
may not be reused. Except for the visible O-ring
EO 177 no spare parts are supplied.
e) In order to avoid media contamination, parts of this
Safety Break normally are not greased.
f) Hold body part in vertical position and center the
circlip inside by hand. Fit the break-away part
carefully from the top into the body. Both have to
be in straight line.
g) Hold parts centric and press them together with a
vise. Make sure that both parts remain aligned
axially until the snap together visibly and audibly.
h) The necessary assembly force has to be applied in
2 steps (two consecutive snaps). In case of noticable
resistance stop and start again at (f).
Thereafter reconnect SSB 16 SS with BS 16 between
nozzle and hose assembly as described opposite and
test assembly for tightness.
