The WHT 007 920 O‑ring is a sealing component for the ABS sensor installation area. Its main functions include:
• Water and dust protection: Prevent rainwater, sand, and dirt from entering the sensor mounting hole, avoiding circuit short circuits or mechanical jamming.
• Corrosion prevention: Block corrosive substances such as brake fluid and salt from entering, extending the sensor’s service life.
• Stable fixation: Use elastic preload to ensure the sensor remains securely positioned, improving the accuracy of wheel speed signal collection.
Although small in size, it is crucial to the normal operation of the ABS system and directly related to the vehicle’s braking safety and stability.
