During changing environmental conditions,pressure can build inside a sealed enclosure,putting stress on seals. Over time stress causes seals to fail,which allows water,corrosive liquids,salt and particulates to enter the enclosure and damage the internal electronics.   With proven performance for more than 20 years, KORE Protective Vents are the leading solution for protecting your sensitive electronics.KORE Protective Vents equalize pressure and reduce condensation by allowing air to flow freely into and out of sealed enclosures. At the same  time, they provided a durable barrier to protect the electronics from contaminants. The result-improved reliability, increase safety and longer product life for your sealed electronic devices.        *Surface of housing must be clean and free of oils . Please contact a Kore representative for housing recommendations and complete installation instructions.   *Suitable for automotive lighting , electronic control modules.     Preparation: Ensure that the vent and housing temperature are >10℃ Ensure that the enclosure's mounting surfaces are smooth        Kore Precision Electronics (DanYang)Co.,Ltd. was established in 2005.After 9 years of development , it has become a uniquely inventive,technologydriven enterprise focused on discovery and product innovation in China . The company is recognised as one of the industry's promising pioneers and has achieved certification of the ISO 9001  , ISO TS 16949 ,and so on .
