About This Item
The Unicel C-7697 is a 7000 Series 155 sq. ft. replacement filter cartridge precision-engineered to fit Harmsco BF155SC filter housings that use the OEM SC/TC-155 cartridge. With 200 pleats of heavy-duty 4 oz. Reemay 2040 polyester media and a 3-1/2" female pipe thread (FPT) top cap, this high-capacity cartridge delivers consistent, high-flow filtration performance for large residential and commercial pool systems.
⚠️ IMPORTANT: Outer Diameter Difference from OEM
The original Harmsco SC/TC-155 cartridge measures 7-3/4" outer diameter. This Unicel C-7697 replacement measures 7-1/2" outer diameter. This difference does not affect fit or performance — the cartridge seals at the threaded top end cap and open bottom end cap, not at the outer diameter. This is a known and accepted dimensional variation for this replacement.
