Inflatable SealsMechanical Research & Design is the industry leader when it comes to producing high quality pneumatic seals, inflatable door seals and other custom air seals.
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.
Inflatable Seal Features:
Inflatable Seals have a Pressure Tight Closure
Featuring the Virtually-Indestructable Inflatable Seals "Double-Acting" Inflatable Ring
Simple Design Minimizes Close Tolerance Requirements (Straight/Curved/Round)
Inflatable Seal Applications:
General sealing and packing
Bulkhead perimeter seals
Automated lifting and gripping processes
Yacht and ship hatch seals
Oil drilling mud containment seals
Industrial leak testing and pressure decay
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.
