I have a Nautilus FNS - 60 diatamaceous earth filter. The large tank seal/O ring came apart. According to the owners manual diagram the part # is 19-5008 and is described as " seal-trapezoid-18 inch dia." Where can I get one of these ?

That ring says it’s,19 and 1/8 inch.  The description on the diagram I have says 18 inches.

It’s the same part number, 19-5008. It will work.
