Abstract
Abstract A self supporting sealing member having a layer of sealant positioned longitudinally between two constraining layers. The lateral dimensions of the sealing member are designed to fit within a hollow member. The constraining layer is preferably a gel having a Voland hardness greater than the Voland hardness of the sealant. This configuration does not allow particles to contaminate the connection of substrates or wires inserted through the sealing member.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
142 words
An assembly for sealing an open end of a hollow member having an inner surface and at least one substrate extending into the hollow member through said open end, which assembly comprises: a) a self supporting sealing member which comprises a layer of sealant positioned between two constraining layers and positioned such that the sealant layer and the constraining layers extend transversely across the open end of the hollow member; and b) a force applying member to move the constraining layers and the layer of sealant into sealing contact with the inner surface of the hollow member; wherein at least one of said constraining layers is sufficiently resilient to accommodate displacement of sealant as a substrate passes through the sealant layer and wherein the constraining layer comprises a gel having a Voland hardness greater than the Voland hardness of the sealant layer.
Claim 2
Dependent Claim
142 words
An assembly for sealing an open end of a hollow member having an inner surface and at least one substrate extending into the hollow member through said open end, which assembly comprises: a) a self supporting sealing member which comprises a layer of sealant positioned between two constraining layers and positioned such that the sealant layer and the constraining layers extend transversely across the open end of the hollow member; and b) a force applying member to move the constraining layers and the layer of sealant into sealing contact with the inner surface of the hollow member; wherein at least one of said constraining layers is sufficiently resilient to accommodate displacement of sealant as a substrate passes through the sealant layer and wherein the constraining layer comprises a gel having a Voland hardness greater than the Voland hardness of the sealant layer.
