FAQ

An inflatable seal is a fabric-reinforced elastomeric tube molded in 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. See Inflatable Seals "101" for more information.

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. Learn more about our rubber seal profile configurations.

The most common inflation medium is air. The specific parameters of the application determine the optimum operating pressure. In some applications, liquid or gel may be used as the inflation medium. Introduction of the inflation medium is through a stem which is usually a flexible hose secured to an integrally molded fitting with a ferrule. A variety of fittings may be attached to the end of the hose.See our typical inflatable seal air connections page for more information

For less demanding applications, there exists the option of using a non-reinforced inflatable seal. Non-reinforced inflatable seals are essentially rubber extrusions that are spliced together and have a valve cured into them. In applications requiring low pressure and low cycles, this approach may be considered. Generally speaking, non-reinforced inflatable seals do not provide the construction integrity and longevity that fabric reinforced, fully molded inflatable seals provide.

Depending on the application, a specialty engineered rubber product, i.e; a bag, compression seal, coupler, cover, diaphragm or rubber gasket may be the solution for your application. Seal Master has the design expertise, and willingness to manufacture unique elastomeric products as required for your application.

YES!!! Essentially all Seal Master® inflatable seals are custom rubber seal designs. With over 30-years in business, more than 7,500 unique products have been developed. For an overview of the process that matches the custom designed seal with your application, please go to our inflatable seal application geometry page now, or contact our sales department at 1-800-477-8436.

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 compression set which negates effectiveness of other seals.
