Great product. Fit as it should. Did not look like the picture. Would be nice if it came with assembly instructions. I was going to return the product, until finding a picture of the product put together. Not like the old style in the picture. The square piece fits over the filter & is to be installed with plumber's tape. The male end connects to the square piece & to the 1/4" feed. Not too hard to install once you know what the pieces are for.
