A water spraying gun 50 has a pivoting coupling between its inlet 40 and outlet 50, so that the angle of the spray relative to the inlet 40 member can be adjusted. A bearing sleeve 70 is provided to reduce or prevent contact between the inlet 41 and outlet 54 members to reduce wear and increase the life of the spray gun 50. The bearing 70 may be made of a wear resistant material. The bearing may be particularly useful when the inlet and outlet members are made of metal. |
