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.
