Patent number: 9599260Abstract: A pipe coupling has an outer shell with a flexible inner liner therein. The liner is secured to the shell by a clamping arrangement, which uses inner rings at the ends of the shell and an inner ring intermediate of the ends. The inner rings are hydraulically expanded out to the shell to form a seal between the shell and the liner at the ends and to retain the liner to the shell at the intermediate ring. In use, compressed fluid is provided to cavities between the liner and the shell to force the liner to seal against a pipe joint. The intermediate inner ring prevents the intermediate portion of the liner from expanding into the pipe joint. A protective handle is provided.Type: GrantFiled: November 6, 2014Date of Patent: March 21, 2017Inventor: Larry D. Howell
