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.
