Fits & replaces
This Excel Filters cartridge (XLS-847) is a direct-fit replacement for Hayward XStream CC1750, CCX1750RE, and Waterway Clearwater II 125 filter systems, cross-referenced with Pleatco PWWCT200, Unicel C-8419, and Filbur FC-1288. Confirm the part number on your current cartridge — or its diameter, length, and end caps — before ordering.
Built to OEM dimensions for Hayward XStream CC1750, CCX1750RE, and Waterway Clearwater II 125 cartridge filter systems, this replacement matches the original cartridge geometry, end-cap style, and media surface area — without the OEM markup. It directly replaces aftermarket Pleatco PWWCT200, Unicel C-8419, and Filbur FC-1288 part numbers — the full cross-reference list is in the Compatibility tab. Every cartridge is manufactured in our Austin, TX facility, ships free, and is backed by the Excel Filters Perfect Fit Guarantee on its listed cross-references.
The XLS-847 1PACK replacement cartridge is engineered for Hayward and built for dependable day-to-day filtration performance. Each cartridge is sized at 8 15/16" diameter x 23 5/16" length, with 4" ID w/ Gasket top and 4" ID w/ Gasket bottom end caps for direct-fit installation with no housing modifications.
Measure your old cartridge cap-to-cap. A variance of ⅛" is normal — anything larger likely means a different housing model.

No — it is an aftermarket replacement cartridge manufactured by Excel Filters in Austin, TX and built to OEM dimensions and media specs. It is not affiliated with or endorsed by the original equipment manufacturer.
Most pool and spa cartridges last one to two seasons depending on bather load and water chemistry. Rinse the cartridge monthly during heavy use and replace it when cleaning no longer restores flow or the pleats show wear.
First double-check the part number on your old cartridge against the Compatibility list on this page — most fit problems trace back to ordering for a different housing model than the listing covers. Our Perfect Fit Guarantee covers the accuracy of our listed cross-references: if this cartridge does not fit a system or part number it is listed to replace, contact us at (888) 532-2801 and we will make it right. Orders placed for equipment outside the listed cross-references are handled under our standard return policy instead.
