  • CONNECTOR, METHOD OF MAKING CONNECTOR AND TUBING ASSEMBLY METHOD
    Publication number: 20220018470
    Abstract: A fitting or connector for use in constructing a tubing assembly is made by bonding an olefin gasket to an end face of a polypropylene fitting member. The gasket is bonded to the fitting member via a heat fusion technique that causes localized melting together of the gasket and the fitting and generates a composite fitting or connector.
    Type: Application
