Benelli TNT125 - Sealing Ring of Fuel Injector; O-Ring Seal Connected to Oil Rail or Oil Injection Cap; O-Ring Seal Connected to Intake Pipe End; Recommended Lubricant

Sealing Ring of Fuel Injector
As shown above, O-ring seal can ensure that
leakage will not occur when fuel injector works within
the range of -40°C -150°C (-40 -
302°F), and it can
resist various fuel additives (such as: ethyl alcohol).
The following data is the existing sealing ring design.

Recommended Lubricant
To facilitate the installation of fuel injector,
lubricant should be applied at O-
ring seal. The
following table shows the list of usable lubricants. Tests
show that the following lubricants do not have any
impact on the fuel injector.

Overvoltage Impact of Fuel Injector
The fuel injector can run at the voltage of 26V and
the working conditions of 100ms (pulse) and 200ms
(one cycle time) for 1 minute at most (run with oil). It
