One listing puts it on the System 3 Modular SMD Series and SD Series D.E. filters. The other lists it under System 3 cartridge filter models S7M120, S7M400, S8M150 and S8M500, and D.E. filter models S7D75 and S8D110. Both readings are given here so you can check them against your own tank, along with the 4.5 inch by 1.25 inch dimensions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is in the box\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe retaining nut alone.
