About This Item
OEM Replacement Lid for Pentair 100 Sq. Ft. Cartridge Filters
The Pentair Lid (59053001Z) is the OEM replacement lid for the 100 sq. ft. configuration of the POSI-CLEAR RP and System:2 Modular Media Filter cartridge filter lines. If your filter lid is cracked, warped, or no longer sealing properly, this is the direct replacement part.
What It Does
The filter lid seals the top of the filter tank, maintaining system pressure and allowing access to the cartridge element for routine cleaning and replacement. A damaged or deteriorated lid compromises the pressure boundary of the filter housing, leading to leaks and loss of filtration performance. Match the part number 59053001Z to your existing lid before ordering — this lid is sized specifically for the 100 sq. ft. filter and is not interchangeable with other capacity models in these series.

Pro Tip
The 100 sq. ft. lid is capacity-specific — it will not fit the 150 or 200 sq. ft. versions of these filter lines. Before ordering, confirm your filter model number (found on the filter label or tank body) matches PXC100 or PLM100. While the filter is open for a lid replacement, inspect the lid O-ring for flattening or cracking and replace it at the same time to ensure a proper pressure seal on reassembly.
