Lebanon client RFQ about rubber cover mold

Hello Anna,

We are fine. Hope all is good at your side also.

Regarding the drawing no we do not have a drawing. The manufacturer is not willing to produce black parts for us or give us the drawing. Therefore, you need to reverse engineer the set.

The important thing is the outside diameter and that the two rubbers fit together so that when they are pressed together, we get a watertight connection. In the rectangular hole there is a switch that fits there, and two wires will pass through the two small holes.

What will be the cost of the drawing?

Melon rubber Reply :
