1. High-efficiency Leak-proof Sealing：Precisely fit the mating surfaces of engine components, effectively block the leakage of engine oil, coolant and other fluid media, ensure the stable pressure and liquid level of the engine's lubrication and cooling systems, and avoid faults such as engine power drop and component wear caused by medium leakage.
2. Temperature & Pressure Resistance：Adapt to the high-temperature and high-pressure working environment of the engine, maintain stable sealing performance in the temperature range of -40℃~120℃ (NBR) or -20℃~200℃ (FKM), withstand the pressure fluctuation of the engine system, and prevent sealing failure under extreme working conditions.
3. Dust & Corrosion Protection：Isolate external dust, sediment and other impurities from entering the sealing parts, avoid abrasive damage to the internal components of the engine; resist the corrosion of sealing parts and surrounding metal components by oil and coolant, and extend the service life of engine related components.
4. Vibration Buffering & Gap Compensation：Utilize the excellent elasticity of rubber materials to buffer the vibration generated during engine operation, reduce the looseness of sealing joints caused by vibration; automatically compensate the assembly gap and thermal expansion gap of components, and maintain long-term reliable sealing effect.
