This Excel Filters cartridge (XLS-928) is a direct-fit replacement for Jacuzzi Triclops TC450 (Oval) Pool Filter filter systems, cross-referenced with OEM Jacuzzi® TC-450. Confirm the part number on your current cartridge — or its diameter, length, and end caps — before ordering.
Built to OEM dimensions for Jacuzzi Triclops TC450 (Oval) Pool Filter cartridge filter systems, this replacement matches the original cartridge geometry, end-cap style, and media surface area — without the OEM markup. It directly replaces OEM Jacuzzi® TC-450 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-928 3PACK 3-pack replacement cartridge is engineered for Jacuzzi and built for dependable day-to-day filtration performance. Each cartridge is sized at - diameter x 28 13/16" length, with Oval Closed top and Oval Open 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.

Can't find your part number? Look it up on the full pool filter cartridge cross-reference chart.
Match the part number printed on your current cartridge against the Compatibility list on this page, or measure the outer diameter, length, and end-cap style and compare them with the Dimensions and Fit tab. A variance of about 1/8 inch is normal — anything larger usually means a different housing model.
It directly replaces 42-3640-15-R, Pureline PL0164. This covers the OEM, Pleatco, Unicel, and Filbur cross-references listed in the Compatibility section on this page.
It fits Jacuzzi Tri-Clops TC450 / TC440 with the original old-style triangular-element manifold when dimensions match. Always confirm against your housing model before ordering.
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. If you still have a fit question, contact us at (888) 532-2801 and our team will help you confirm the right cartridge before or after you order; returns are handled under our standard return policy.
