Product overview
6CH-940 is an aftermarket pleated hot tub filter cartridge, 6 in. in diameter and 8-1/4 in. long, with 45 sq ft of filter area. Top: semi-circular handle. Bottom: injection molded 1-1/2" SAE thread.
It interchanges with Pleatco PWW50P3 and Filbur FC-0359.
OEM cartridges it replaces: Aber Hot Tubs 03FIL1400; CMP 25252; Rec Warehouse 378902; Vita Spas PWW 50; Waterway 817-0050.
Fitment notes: Apollo Spas: Two 50 sq.ft. cartridges required (used side-by-side). Canspa Mfg.: Two 50 sq.ft. cartridges required (side-by-side). Master Spas: For use in Master Spas swim spas.
Before ordering, measure the old cartridge — overall length, outside diameter and both end fittings. Some catalogs quote the length of threaded top-load cartridges with the thread and some without, so a quarter-inch difference between listings is common. We supply spa service companies, dealers and online retailers: MOQ 50 pcs per part, mixed cartons welcome, and single samples to confirm fit before a production order.
