Seal Ring, injector - 9001-850K DELPHI

To create a hermetic fit of the nozzle, special O-rings are used. They are made from rubber. Nevertheless, over time, this material loses its original properties. This is due to natural aging. As a result, air leakage or fuel smudges occur. The consequences of wear of the corresponding seals can be eliminated only by replacing them. Therefore, it is recommended to periodically change the nozzle rings. We must not allow the loss of their tightness. A competent approach will ensure the normal operation of both the fuel system and the passenger car as a whole.

The operation of the injector seal rings

Today, O-rings are present on gasoline and diesel DELPHI brand Seal Ring, injector. They help to eliminate air leakage, as well as fuel leakage directly at the points of connection of the nozzle with the fuel line. Currently, seals are most often made of rubber, due to:

1. the absence of large mechanical loads;
2. a small temperature effect (there is a certain distance to a hot engine);
3. high elasticity of the material;
4. slow loss of original properties under the influence of an aggressive environment.
