Abstract

Between the hydraulic high pressure body (3) and the securing nut (11), is a bush (1), whose outer diameter equals the inner diameter of the body (3) upper part, and whose inner diameter is the same as the outer diameter of the pipe (2) to be fitted. The bush (1) has a blunt conical cross-section in its upper part and a flange (4) at its top end. Also between body (3) and nut (11) is a sealing ring (8) the lower part of which engages in the bush (1) at a point which is conical and can be bent inwards. The top edge (9) of the ring (8) encompasses the pipe (2) and is inclined so that it may locate on the cone provided in the nut (11).
