Overview
Overview
Cartridge length × outside diameter: 20-inch manufacturer length; outside diameter unverified. Partial or unverified dimensions. Nominal size classes may differ from measured end-to-end dimensions.
FT-FTC-5BB20 is the 20-inch, 5-micron Big Blue cartridge identified in the Landbased 1800/4000 Connect parts drawing. The drawing separately identifies its 20-inch three-piece housing as FT-FTH-20BB3PCS.
This listing is the replacement cartridge. The housing, fittings and hoses called out around it have their own part numbers.
Match the 20-inch length and 5-micron grade to the system arrangement. A 10-inch Big Blue cartridge is a different length even when its filtration grade matches.
