Ball Joints


DMI's standard line of LockMaster, locking ring type, balljoints are available in sizes from 6-inch thru 30-inch. No other flexible pipeline connectors can match the DMI LockMaster balljoints for simplicity in installation or long wearing trouble-free performance under harsh conditions. They feature quick connecting and disconnecting action, elimination of eyebolt maintenance and offer construction of the highest quality materials.

Other sizes and styles of balljoints including StormMaster and LinkMaster as well as stern swivels are available from DMI.
