  • Adjustable length piping union
    Patent number: 5024469
    Abstract: An adjustable length piping union having telescoping tubes. An inner tube has outer ring grooves whose bottom walls slope, and whose axial width is greater than the width of an O-ring contained in them. This enables an easier reduction in length than increase in length. A ledge permits passage of the rings for assembly, but frustrates the separation of the tubes.
