AGM Start-stop vent plug
Company profile:
Zhongshan Oursun New Energy Co., Ltd. is a ISO-certified manufacturer specializing in advanced battery components. Located in China. We are professional to manufact battery status indicators and battery safety valve, AGM Start-stop vent plug, bushing, battery box . All products are independently researched and developed, designed and produced, and have some technical patents.
The AGM Start-stop vent plug is sturdy and durable with an excellent finish that gives a long service life. There is a built in PE filter that ensures it provides a splash proof or anti splash feature. It is because of the filter that corrosive acid fumes do not escape and become the cause of a fire hazard and helps keep the battery exterior completely dry. By arresting the acid fumes damage to costly equipment around the battery can also be prevented.
