Fabric-reinforced, rubber inflatable seals prevent leaks and work in even the toughest of environments.
During a two-part video series, I had a chance to sit down with Paul Heney, Design World’s editorial director, to take a look at a variety of inflatable seals from Seal Master. The fully molded and custom-engineered rubber seals form a tight barrier between a mounting and striking surface.
The company says it has created more than 7,500 different seal configurations and the key to these designs is their unique and complex geometries — ranging from round to flat and 90-degree angles to cylindrical shapes, and more.
These seals are ideal for pushing, pulling, squeezing, holding, lifting, and of course, sealing components and compartments in many manufacturing processes, from hydraulics to doors on aircraft. They can also serve almost as an actuator in assembly and other manufacturing processes to stop functions.
Designed with unique cross-section geometries, these seals can inflate and deflate in three basic directions of operation: axial, radial-in and radial-out. Common materials used in their design include Butyl, natural rubber, Nitrile (Buna N), Silicone and many more. The fabric reinforcement is often made of Dacron, Kevlar, Nomex and Nylon.
Watch the following video demonstrations to see how integrally molded air connections quickly inflate seals and make an air-tight hold, even on tight angles.
