Abstract
An environmental connector formed by insert molding a thermoplastic rubber insert into a plastic cylindrical housing having an external shoulder adjacent to an exit aperture for the thermoplastic rubber to flow to an annular void in the cavity of the mold. In such manner, an annular ring such as a gasket or o-ring is formed by the insert molding process, and is connected as one piece with the thermoplastic rubber insert formed in the internal chamber of the housing. The housing is made of polypropylene and the thermoplastic rubber is Santoprene so the two materials stick together to hold the annular ring snugly against the shoulder. The insert of the female connector has a concentric opening to receive the housing of the male connector, and the concentric opening terminates in thin protrusion that is compressible to from an inner seal to prevent the ingress of moisture into the connectors.
