Replacement Filter Cartridges
Replacement cartridges for the Jacuzzi® Tri-Clops filter line — round elements for the TC330/TC440/TC550 style and oval elements for the original TC300/TC450/TC600 housings. Every Tri-Clops filter takes three cartridges; the compatibility chart below the products shows both element styles.
No cartridges match these filters.

Excel Filters makes replacement cartridges for every Jacuzzi® Tri-Clops filter: round elements for TC330, TC440, and TC550 housings and oval elements for the original TC300, TC450, and TC600. Each Tri-Clops housing takes three cartridges — our 3-packs replace the full set at once.
Tri-Clops filters use three cartridges per housing. Original TC300/TC450/TC600 tanks shipped with oval cartridges; the round-cartridge style fits TC330/TC440/TC550 housings, or an original tank after the Jacuzzi® manifold conversion kit is installed.

Only if the housing has been updated with the Jacuzzi® stand-pipe conversion kit. Original TC300, TC450, and TC600 Jacuzzi® Tri-Clops housings were designed for the oval/triangular cartridge style and use a different internal stand-pipe configuration.
If your housing still has the original stand pipe, order the matching oval Tri-Clops 3-pack. Round cartridges will only fit after the round stand-pipe conversion has been completed.
Jacuzzi® Tri-Clops filter housings use three cartridges per system. Excel Filters Tri-Clops replacements are sold as 3-packs, allowing you to replace the complete cartridge set at one time.
Replacing all three cartridges together helps maintain consistent water flow and filtration performance.
The easiest way is to look at the shape of your existing cartridges from the top:
The housing model often indicates the cartridge style, but always confirm the cartridge shape and stand-pipe style before ordering.
