This is just a pvc threaded reducer adapter. You will need to turn the threads down several thousandths on a lathe for it to screw into the large reducer. I had to turn the washers down in a lathe to make a groove for the samll screen, and then rivet them together with brass pins. A screen that just fits into the adapter would work just as well.
