The Engine Sensor Seal O Ring is used in the connection between a sensor and a screw connected to the engine block. It is used to create a tight seal between the sensor and the screw, preventing contaminants from entering the connection. It is placed on the screw before it is threaded into the engine block. It ensures that no fluids or contaminants can enter the connection, which is for accurate sensor readings and proper engine function.Attributes:• Withstands the pressure and temperature conditions present in the engine• Manufactured to precise specifications and are built for durability and reliabilityApplications:The Engine Sensor Seal O Ring is used to fill any gaps or irregularities between the mating surfaces, ensuring that no fluids or contaminants can pass through between the sensor and engine block sensor port.
