Inflatable Seals and Gaskets

Why Choose Inflatable Seals and Gaskets

An inflatable seal is a type of rubber seal which inflates (rather than compresses) to create an air or watertight barrier. When compared to elastomeric compression seals, inflatable rubber seals are more forgiving of irregular or misaligned surfaces, which boosts sealing integrity.

They are also easier to use because they require less force to ensure a good seal – just move the mating parts into place and inflate the seal to close the gap. This makes them the perfect solution for unique and/or difficult sealing applications.

Where Inflatable Seals and Gaskets are used

Our inflatable seals are being used today in environments where cleanliness and containment are paramount.

• Kevlar® fabric reinforced inflatable EPDM rubber airlock seals to seal out radiation in nuclear power plants

• Low smoke silicone inflatable seals for sliding passenger doors on commuter trains
• USP Class VI (i.e. medical grade) inflatable seals for large pharmaceutical washing equipment

• Inflatable hopper seals used on powder handling equipment

• Large inflatable door seals (greater than 100 LF in circumference!) for aircraft hangers
