Abstract
An over-molded gland seal for producing both a fluidic seal and a fluid conduit. The apparatus includes a substrate having an elastomeric layer over-molded thereon and an elastomeric gland seal molded into the over-molded layer. Another aspect of the apparatus includes a host-part having a raised wall thereon, said host-part receives the elastomeric gland seal and compresses the gland seal with the raised wall. The substrate, the gland seal, and the host-part define an enclosed region. To form the fluid conduit, the apparatus includes a fluid inlet port and a fluid outlet port that communicate with the enclosed region.
