Generally a wiper can be easily fitted into the closed housing by deforming into a kidney shape. It is very important that the assamply tools are made of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
We can also produce this wiper on request in the materials below. This is our type DA101.
