How Pneumatic Seals / Inflatable Seals Work

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.

Strips can be in closed ends, mitered ends, and continuous loops. Mechanical Research & Design can produce inflatable seals from many elastomers including Butadiene Styrene (SBR), Chloroprene (Neoprene), Ethylene propylene (EPDM) and Fluorinated Hydrocarbon (Viton®). Viton(R) is a registered trademark of DuPont Dow Elastomers.

Inflatable seals accessory items such as machined seal housings and inflation control devices are available. Inflatable seals are available for immediate delivery from stock. CUSTOM SHAPES AND SIZES ARE ALSO AVAILABLE UPON REQUEST.
