18. – the bottom outlet version of this filter is obsolete and no longer available – R172502B . If you need this type of filter assembly, you can use this R172504B – This replacement has the same function but does have some differences. 172504B has the same canister dimensions as the 25 sqft version, But is a 50 Sq Ft Cartridge and will need reducers 437-251 since this is 2″Slip and the discontinued 18 had 1 1/2 inch connections.
We also offer the Chemical Dispenser lid- R172540.
