Let's Design Something » Seals are described by their cross-sectional profile, critical feature dimensions, and their material. These combinations create near infinite variety of seals to handle any requirement. This wasn’t always the case: Originally created from greased leather and cork packings or gaskets it’s easy to understand why those classic Victorian steam locomotives leaked so much steam! As internal combustion engines took over from steam so the corresponding seals needed to perform to higher temperatures and pressures, while resisting hydrocarbon fuels and lubricants. Synthetic molded seals produced to standardized formats started gaining broad acceptance in the 1940’s especially as aerospace applications routinely pushed new limits. New elastomer and thermoplastic recipes continue to be developed, providing improved physical properties as industrial and consumer continue to proliferate. There’s a variety of seal types and materials suited for any given application. Understanding the difference between what works OK vs what will allow your new product to run longer, hotter, faster, deeper, using less energy than the competition – that’s where the BEST seal comes into its own. We’ll help you find it. There are an infinite number of profiles ranged on a continuum from simple “O” or square profiles all the way through pressure activated lips, spring energizing elements, and load balancing undercuts and in-gland stabilization features. Please use our Seal Materials Resources as a starting point. Consult with our applications engineers to get you over the finish line.
