How Do Inflatable Seals Work? And Their Application

Inflatable seals are designed to seal a gap after being inflated. The gasket is flat shaped, with a rubber flange to facilitate installation. During inflation, the flat gasket expands to a larger thickness and the sides will deform into a circular shape. The gasket is provided with ridges on the upper and lower contact area to improve sealing capacity. The gasket can be inflated by fluid

Western Rubbers are well known Inflatable Seals Manufacturer in the rubber industry. Inflatable seals manufactured by Western Rubbers are designed to provide a clean, time-saving solution to hermetic sealing against, powders, granules, gases, liquids, and dust. These seals are most useful to seal fabricated pieces of equipment.

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.

Inflatable Seal Manufacturer

Inflatable seals are designed to provide efficient hermetic sealing solutions providing protection against incursions by powders, granules, gases, liquids, and dust.

These pneumatic airtight seals are extremely useful for sealing fabricated pieces of equipment where:

·          the sealing gap might vary

·          assembly and dis-assembly needs to be quick and simple

·          hygienic procedures exist (FDA applications and regulations)

Generally working from within a specific groove size the seals can operate axially, and for both inward and outward radial movements. The most popular requirements are for FDA approved Silicone Elastomer in either Blue, White or Red iron oxide colours. Other Elastomers and Pigmentations are available for a wide variety of sealing applications.

Bond most types of the available inflation connectors to the seals as required by the customer/application. This process bonds the connector to the seal by localized injection of identical compound vulcanizing the connector to the seal. The strength of Vulcanized Connector far exceeds any mechanical fixing or adhesively bonded connector, associated with this type of seal. Inflatable Seal Manufacturer has independently pressure tested and supplied with a supporting ‘Test Certificate’. 

These tests on free-standing, unsupported seals vary from 1 bar to 4 bar pressure, dependent on the profile type and/or customer specification. With the aid of purpose designed test rigs, which enclose the seal, our production techniques are tested and supported with the proven case history.
