I would like to confirm that this is the correct gasket o-ring for the Nautilus NS-60 DE Filter. I think I've been trying to get a wrong sized one to work for years......
O-ring, Filter Tank 18-5/16" ID, 9/16" - P24225 O-86 4672-07
Shipping: Ground
Qty: 1
Price: $22.99
Total: $22.99
And the label on the bag also has "APC02374" "P24225 Purex O-Ring"
Thanks to the chat folks who helped me figure this out.This stainless steel filter is from the 1980's.
