Proven in the Pas t …
Building upon three initial unique designs (Omniseal®, RACO® and TEC Ring seals ), we have been recognized asa leading designer and manufacturer of high-performance spring-energized seals that provide improved sealing
performance over soft elastomeric seals and hard metal gaskets in applications involving cryogenic liquid propellants invarious rocket engine programs. Our Meldin® thermoset polyimide material is ideal as finished machined components
in high temperature as well as a lightweight and dimensionally stable bushing, piston ring, guide ring, split ring typeapplications and other custom shapes.
