The valve oil seal is a precision oil supply controller. It has good resistance to positive and negative pressure alternation, eccentricity and high temperature. It is widely used in diesel engine, gas engine, methanol engine and gasoline engine.
Used in gasoline engine, diesel engine and CNG / LNG engine, high temperature resistance can reach 200 ℃. Resistance to positive and negative pressure alternation and eccentricity. Meet the operating conditions of different models, including truck crane and cold chain logistics vehicle idling for a long time. The valve oil seal with ternary fluororubber can meet the requirements of 2 million km, which is mostly used in the engine of express vehicles.
