Details

Automotive parts oil cup cover，Usually refers to the brake fluid reservoir cap of the braking system, and can also refer to the engine oil filler cap. It is a key small component that seals the liquid storage tank, maintains system pressure and cleanliness.

Sealed and leak proof: prevent brake oil leakage and prevent dust/moisture from entering (absorption of brake oil can cause a decrease in boiling point and brake failure).
Pressure balance: Equipped with a built-in breathable valve/one-way valve, it balances the pressure difference caused by the thermal expansion and contraction of brake oil, ensuring the normal feel of the brake pedal.
Liquid level observation: Some parts have scales or transparent windows for easy inspection of brake oil level.
structural composition
Cover body: engineering plastic (PP/PA), oil resistant, high temperature resistant and aging resistant.
Sealing gasket: Nitrile rubber (NBR)/fluorine rubber, resistant to brake oil corrosion, ensuring a tight fit.
Pressure balance valve: one-way valve/breathable membrane, allowing air to enter and exit, preventing oil leakage and water vapor from entering.
