Abstract

Abstract Sealing means for forming a seal between an aperture in a panel or the like and a conduit or the like which passes through said aperture. The sealing means includes a compressible grommet located in the aperture and having adjacent washers alongside the grommet. The washers have peripheral slots which extend inwardly at different angles and in which slots the conduit is located, thus, the washers abutting against one another with their differently inclined slots act to generally close off each other''s slots and the washers are compressed against the grommet so the latter seals against the aperture in the panel.

Claim 1
Independent Claim 183 words
Sealing means for forming a seal between an aperture in a panel or the like and a conduit or the like which passes through said aperture, said means comprising, a compressible grommet of a size which can be inserted in and substantially fills said aperture, a hole through said grommet and through which said conduit passes, a plurality of washers each having a slot therein which extends from the periphery of said washer and inwardly at an angle inclined to the radius of said washer and terminating in a slot end, said slot ends being in axial alignment with each other and also with said grommet hole and said conduit being located in said slot ends, the slots of adjacent washers being inclined at different direcTions from one another whereby adjacent washers abut against one another and overlap a portion of each others slots, said washers and grommet also each having a generally central opening extending therethrough and in alignment, and means extending through said aligned openings for compressing said washers and grommet together to create a seal between said panel and conduit.
