A fabric-reinforced inflatable seal is an elastomeric tube molded into a concave, convoluted or flat configuration. It is designed to round out with the introduction of an inflation medium to form a tight barrier between a mounting and striking surface.

An inflatable seal operates by introducing an inflation medium. Upon introduction of the inflation medium, it quickly expands to the striking surface, affecting a positive seal. When the inflation medium is removed, the seal retracts naturally to the deflated molded configuration. This provides clearance for free movement of one or both surfaces.

An inflatable seal has several advantages over other sealing methods:
• It provides a leak-proof closure, yet allows clearance when needed.
• It simplifies the design of the structure and hardware.
• It minimizes the need for close machining and/or fabricating tolerances.
• It is not subject to a compression set which negates effectiveness of other seals.

Yes! Essentially all Western Polyrub Inflatable seals are custom rubber seal designs. After over 30-years in business, more than 8000 unique products have been developed. Take a look at all of the unique designs at inflatable seals product category.

It’s important to consider the application’s environment: gas temperature, radiation and abrasion exposure when maintaining your inflatable seal. Learn more about these application environmental considerations.

Generally for nominal pressure applications we suggest customers to avoid fabric reinforced seals so as to avoid high costs. But if your differential pressure requirements are higher than 7-8 Bar then we suggest customers go for fabric.
