The SAFETY SWIVEL BREAK 'SSB 25' is a self-sealing reusable break-away coupling
(type 1 to EN 13617-2) 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 25 nozzle. Before delivery each SSB 25 is tested regarding the break-off and tight-
ness under pressure (5.25 bar acc. to standard EN 13617-2). This is documented by the
factory date code, e.g. '191211' for 19 = Year ( YY ), 12 = Month ( MM ), 11 = DAY ( DD ).
According to EN 13167-2 the coupling separates at a pull force between 80 kg (800 N) and
150 kg (1500 N) in an axial and angular direction. Temperature range -20° C up to +55° C
( LT-Type -40° C up to +55° C ).
NOTE: Ensure that the dispenser allows the maximum pull force in all approach directions
without damage.
An integral valve at the break-away part stops the flow of fuel at the hose end. According to
safety regulations max. 120 ml are allowed to flow out. After separation the SSB 25 must be
reassembled by an authorised service engineer according to the instruction (opposite page)
and may then be used again after leakage test. The construction is such that fluid is not
sprayed out during reconnection action.
INSTALLATION INSTRUCTIONS
Switch off pump. Release pressure in hose.
l
Remove nozzle from hose assembly and drain hose.
l
Remove existing swivel from nozzle.
l
Push break sleeve BS 21 back over the hose assembly (and anti-kinking sleeve KS 21).
l
Slightly lubricate thread; screw SSB 25 with assembled strainer into nozzle.
l
Lubricate thread and screw SSB 25 onto the hose assembly by using two
l
EW - M 36/41 or EW - M 41/46 wrenches, not a vice.
Prime pump and check carefully to ensure connections are tight.
l
Push BS 21 over SSB 25 until the lip rests in the groove.
l
If the SSB 25 was factory fitted to the nozzle, the assembly on the hose is done the same
way as described above.
The drawing below shows the assembled system with the correct position of the strainer.
The break sleeve BS 21 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 to prevent misfuellings.
