Lee Multiseal

The Lee MultiSeal® is a new sealing concept based on the controlled expansion of a cylindrical polyamide-imide sealing element, eliminating conventional O-Rings and Anti-Extrusion Rings. The MultiSeal radically simplifies port layout, and offers significant space savings, reduced machining costs and higher reliability than traditional sealing methods. The ability of the MultiSeal to seal radially and axially gives designers the freedom to locate ports within a manifold in the most flexible, compact and economical way. Full details have been published in SAE paper #912134 "Total Flexibilty in Cartridge Valve Porting Through Innovative Sealing Technology".
