Pentair 50 and 100 Sqft Clean & Clear Tank Lid

The Pentair 50 and 100 SqFt Clean & Clear Tank Lid (part number 178553) is a heavy-duty upper housing dome engineered specifically for Pentair Clean & Clear, Clean & Clear Predator, and Warrior single-cartridge pool and spa filtration systems with 50 and 100 square foot capacities. Injection-molded from a high-strength, fiberglass-reinforced polypropylene composite, this almond-colored replacement lid serves as the upper pressure vessel shell, securing directly onto the matching tank bottom via a heavy-duty locking ring. The top apex of the lid features factory-molded ports explicitly designed to house the manual air relief valve and pressure gauge assembly, allowing operators to monitor and regulate internal tank conditions safely. Built to maintain absolute structural integrity under continuous internal hydraulic pressures up to 50 PSI while resisting harsh outdoor UV weathering and corrosive pool sanitizers, this durable lid provides an absolute airtight and watertight seal when properly clamped. This robust, pressure-rated upper shell carries an approximate product and shipping weight of 5.80 pounds, providing the heavy-walled strength required for high-velocity filtration systems while remaining easy to lift and remove during routine cartridge maintenance.
