The water hose (2) is connected by a ripple unit (1) which consists of a cylindrical metal sleeve (3) sliding over the hose end, and which has an inward bent shoulder part (4). The open end of the hose has a screwed-in sleeve (5) retaining a metal sleeve (3). A nipple nut (9) retains both sleeves. An engine bearing ring (13) encompasses the screwed in sleeve with a slight clearance, and supports a sealing ring (17). The nipple nut has an inner thread which when pulled tight seals onto the seal ring. A ball bearing unit (21) fits in the screwed sleeve part (18). |
