I am updating a product made from molded plastic components. Currently the product is IPx2 and it needs to become IPx4.
Please, bear with my explanation, I will not be able to post any images or parts of what I am working with.
The product has a front half, a rear half, and a middle portion sandwiched between the top half of the front and back. The current method of sealing involves applying a "wet seal" onto the edge of the plastic components. Our manufacturing and service departments have requested we switch to a sealing method that is more easily removable (e.g. o-ring, overmolded seal). So this method should be avoided going forward.
I am struggling to figure out how to handle the gap that will exist at the "T" junction. The top of the "T" is a continual edge that has a shape similar to the edge of a hard preformed taco shell. The lower portion of the "T" is a simple "U" shape with the tops of the U touching the bottom portion of the "taco".
How do I close up the pinhole that will likely exist in between the two sealed geometries?
Is there a possible custom 3 dimensional o-ring that can handle this geometry?
