American Seal & Engineering designs and manufactures metal seals and sealing systems for high-tech automotive and diesel markets. Our products are used in Formula One racing cars and high-tech diesel engines around the world.

Most of the metal seals we develop for the automotive industry are custom designed for specific program design envelopes.

Use Case

For instance, a major engine OEM engaged American Seal & Engineering to provide an engineered solution to reduce their emissions before a government-mandated deadline in order to avoid severe penalties. Our engineering team designed and developed a beta and alpha sealing system in just nine months. Our product provided the solution for our customer with the added benefit of increased performance while also maintaining current fuel efficiency; this contrasted with our customer’s competitors who experienced a fuel efficiency decrease. Our manufacturing team introduced the new product into the production line one year ahead of schedule and at a cost savings to our customer in excess of $1 million – an achievement never before realized by this OEM.
