Abstract : A gasket for watertight/airtight sealing of individual-acting movable structural closures (such as shipboard doors, hatches and scuttles), featuring utilization of silicone rubber material in a specifically proportioned rectangular-parallel-epipedoid shape having two 45 deg chamfers and a lengthwise intermediate semicylindrical groove. The gasket's superior sealing properties derive from its configuration and composition as well as its resultant unsusceptibility to permanent set. The gasket is softer and hence easier and quicker to install, performs better in a fire environment, has a significantly longer life expectancy, requires far less maintenance and overall affords substantial savings.
