Products Description
Brake master cylinder joint connector rubber rings are specially designed for the connection between the master brake cylinder and hydraulic pipes or other components of automobiles. Its core function is to form a dynamic seal through highly elastic rubber material to ensure that the brake fluid does not leak under high pressure, thus ensuring the sensitivity and reliability of the brake system.
Features
- High-Temperature Stability:
It can maintain elasticity in the range of -40°C to 150°C, adapting to the instantaneous high temperature generated by brake friction.
- Oil and Corrosion Resistance:
Brake master cylinder joint connector rubber rings have a strong tolerance to brake fluid (DOT3/DOT4), grease, and chemical solvents to avoid swelling or aging.
- Anti-Wear Design:
Special surface texture treatment reduces friction loss with metal parts and extends service life.
- Strict Size Matching:
It is formed by precision molds with tolerances controlled within ±0.1mm to ensure the perfect fit with different models of brake master cylinders.
- Dynamic Sealing Ability:
It maintains sealing integrity under hydraulic fluctuations or vibration conditions to prevent micro-leakage.
Functions
1. Hydraulic Seal
Brake master cylinder joint connector rubber rings form a flexible barrier between the brake master cylinder and the pipeline, withstand hydraulic shocks up to 20MPa, and ensure that the pressure is transmitted to the brake caliper without loss.
2. Anti-Pollution Barrier
Prevents water vapor and dust from entering the brake fluid circuit, preventing internal valves and pistons from rusting and jamming.
3. Shock Absorption and Noise Reduction
Absorbs mechanical vibration during brake pedal operation, reduces the probability of abnormal noise, and improves driving comfort.
Material characteristics
The hydrogenation treatment of HNBR makes it perform well in high temperature and chemical environments, better than traditional nitrile rubber. It has high mechanical strength and tear resistance, and its anti-aging and anti-wear properties make the service life of HNBR seals longer.
