This product is a non-asbestos/rubber gasket exclusively for construction machinery, designed for heavy equipment such as excavators and loaders. It is used in connection parts like hydraulic pumps, engines, and pipelines to provide sealing, leak prevention, shock absorption, and noise reduction. Manufactured from high-quality nitrile rubber (NBR) or composite fiber materials, it features excellent elasticity, oil resistance, and temperature resistance, effectively resisting the erosion of engine oil, hydraulic oil, and high-temperature conditions. Precision stamped for high dimensional accuracy and excellent fit, it maintains reliable sealing under high pressure and vibration, effectively preventing fluid leakage and extending equipment service life. It serves as a direct replacement for OEM parts and is widely used in the maintenance and repair of construction machinery brands.
