Silicone Inflatable Gasket

Pneumatically inflated silicone seal profiles that expand to close large gaps.

Advanced pneumatic sealing profiles that expand when inflated with compressed air (1 to 3 bar) to form a bubble-tight barrier between separating doors and domes. Rapidly deflates when air is vented to allow zero-friction door opening.
