Because older Nautilus, Nautilus FRP, FNS, and related Pentair filter families use several different tank-seal part numbers, O-487-0 should be selected by the exact filter model and OEM reference rather than by appearance alone.\u003c\/p\u003e\u003cp\u003eIf a Nautilus filter is leaking at the tank seam, inspect the existing tank O-ring and sealing surfaces for flattening, cuts, stretching, distortion, debris, or incorrect seating.
