Hydraulic/Mechanical Components DEF Nozzle
DEF Nozzle
The DEF nozzle is designed to dispense DEF. No other nozzle type is currently approved. The
DEF nozzle is manufactured by Elaflex/OPW (Elaflex Slimline ZVA).
• The nozzle is a non-vapor recovery nozzle. Conventional performance and
troubleshooting procedures for non-vapor recovery nozzles are also applicable to the DEF
nozzle.
• In addition to fluid compatibility, some nozzles require a ring magnet to be slipped over
the spout to dispense DEF. Normally this ring magnet is part of the construction of the
vehicle DEF tanks. It helps to prevent DEF from being dispensed into the diesel tank that
will result in severe damage to the engine. The technician must have a ring magnet or its
equivalent to dispense DEF through the nozzle during tests. The test ring magnet
(M10656B001) is available from Gilbarco.
• The nozzle handle also contains the activation magnet that is part of the pump handle
system.
• The nozzle can freeze if the cabinet heater fails, power is lost, or the nozzle door does not
drop down completely during cold weather. The nozzle must be checked for leaks and
operation after thawing.
Nozzle Door Mechanism (Cold Weather Units Only)
The Nozzle Door Mechanism protects the nozzle, hose and breakaway from freezing by
retrieving the components into the heated cabinet and covering them with a drop down door.
• The door mechanism must drop down completely without assistance to cover the nozzle,
and so on when holstered. For cold environments if this does not happen, the nozzle, hose
and breakaway may freeze. If the door does not close on its own, repair is required.
• When using the nozzle always maintain control manually of the nozzle as the hose
retriever could pull the nozzle out of the tank, prover or other receptacle.
• Missing or damaged curtains must be replaced.
• Curtains must close completely to ensure heat is retained in the nozzle vicinity or nozzle
freezing may occur during very cold weather.
