Inflatable Seals

Inflatable seals or pneumatic seals work by introduction of an inflation pressure into the cavity of the inflatable seals. This inflation pressure causes the displacement of the seals effecting a positive seal between the seals and the surface to be sealed. Once the seals inflation pressure is removed the seal returns to its uninflated position (memory).

Regulated air is the commonly utilized inflatable seals medium while in some applications pneumatic (gas) or hydraulic (liquid) methods are suitable. Inflatable seals offer versatile configurations in three different planes: radially in, radially out, and axially.
