ABSTRACT:
Apparatus seals holes in an airplane bulkhead and provides for the passage through such holes of members (e.g. electrical wires) furnishing utilities to the airplane. The apparatus includes: 1. A hollow sleeve made from a light, strong and stable material (e.g. titanium) to provide a conduit for the utility members; 2. A relatively hard (e.g. 90 durometer "A") grommet having an internal opening and with an axially extending recess for disposition on the bulkhead with the bulkhead hole in the recess; and 3. A compliant (e.g. 55 durometer "A") gasket with internal opening to receive the sleeve in tight fit relationship. The gasket is provided with first and second portions each having an external periphery with a diameter greater than the diameter of the internal opening in the grommet. The gasket has an external recess axially defined between the first and second portions to receive the grommet at the internal opening in the grommet. The first portion may have voids and an external diameter to provide for a compression to a diameter no greater than that of the external recess. This facilitates the disposition of the grommet on the gasket with the internal opening in the grommet disposed in the external recess in the gasket. The gasket may be cut radially between its external periphery and its internal opening to facilitate the disposition of the gasket on the sleeve. The grommet and the gasket are provided with novel compositions and are made by novel methods.
