I have the pictured Nautilus pool filter. I'm looking for the O-ring that joins the filter elements to the white vertical pipe. The pipe measures 2 3/8 inches in diameter with a 0.130 diameter wide by 0.080 deep O-ring groove. As the picture shows, the unit appears to have been manufactured in June, 2005. What do I need for an o-ring?
