CANADIAN PATENT APPLICATION OF ISAK KREKU AND LARS KENNETH LENNARTSSON FOR A PIPE JOINT SEAL Abstract of the Disclosure A pipe joint seal comprises an insert adapted to be mounted around the joint and the pipe sections adjacent thereto and having in its inner side dovetailed grooves or the like which are filled with a plastic sealing compound. The insert can be clamped around the pipes and the joint by means of a sheet-metal union piece having bent edges to form a channel within which said insert is mounted. When the insert is tightened around the pipes, the sealing compound urges the insert portions defining the dovetailed grooves tightly against the pipes so that a satisfactory seal is obtained also on uneven pipe surfaces. By designing one bent longitudinal edge of the union piece with a height greater than that of said insert, and by causing said bent edge to engage with a groove in one of said pipes, the seal can be simply and conveniently held in nondisplaceable engagement with said pipe, while the other pipe is displaceable in the seal.
