Inflatable Door Seal

Inflatable Door Seal


The inflatable door seal is used in advanced applications where perfect sealing of door is required.  In industries like pharmaceutical, chemical processing,  nuclear power and other such industries sealing is critical. To prevent contaminants from entering a particular room, engineered rubber products like inflatable seals find its applications.For high-pressure sealing, reinforced inflatable rubber seals are used. These inflatable seals are inflated upon door closure to seal the gap between the door and its surrounding frame. The property of rubber is such that is expands to completely cut off and isolate the entire room. Hence these molded rubber seals are best suited for such advanced applications.
