An injector is a device designed to supply fuel under pressure to a vehicle engine. The O-ring is designed to seal this device. With its help, the flow of liquid fuel and the penetration of air into the places where the nozzle and fuel pipe are connected are prevented.

To prevent unpleasant situations associated with the failure of the car, it is necessary to change the gaskets under the nozzles in time.

The functionality of the CORTECO brand Seal Ring Set, injector

The seal is installed at the top and bottom of the nozzle. Top seal rings are installed on gasoline and diesel injectors. Inlet seals are made of rubber, because they are not affected by high temperatures and there are no heavy loads. Such products slowly lose their properties under the influence of the environment.

The bottom seal rings are exposed to conditions that are more aggressive. Based on the material that was used in their production, they are of the following types:

1. metal;
2. copper;
3. rubber.

Two seals can be installed at the same time, for example, elastic and metal, in order to increase reliability and ensure high tightness of the entire system.
