The part is not a genuine Nissan part. It is made in China and there are a few differences between this one and the real one. Will be returning the part.

The valve itself is fine and has been working great. The issue is the seal. The seal does not fit into the grooves of the valve well. It's slightly smaller than the surface area and I had to use a flexible sealant to help to keep it in place.
