  • Stab joint coupler
    Patent number: 5257836
    Abstract: A stab joint coupling, for joining corrugated pipes, has a male connector and a female connector both having means for attachment to a first and second piece of pipe by engaging the corrugation of the pipe. A circumferential elastomeric sealing means is positioned between the joined coupling connectors to effect a substantial liquid seal for the joint. The coupling permits two pieces of corrugated pipe to be joined relatively inexpensively and quickly by workers in the field.
