Virgin DI Resin, Ready To Install

Each cartridge arrives filled with Tucker's virgin DI resin in a 4" x 21", 4" x 30" or 4" x 40" size. Fresh DI should read 0 ppm TDS, and the reading climbs as the resin is used up.

These are one-time-use cartridges: once output rises above 10 ppm and glass starts to spot, you swap in a new one instead of refilling it. A TDS meter on the outlet tells you when.

Sized For Standard 4" Housings

Sized For Standard 4" Housings

The 4" x 21", 4" x 30" and 4" x 40" cartridges fit the matching housings from many manufacturers. The 4" x 30" also fits Tucker's 4060, H2Pro and T-DI systems.

Measure your housing before you order: the 4060 takes the 30" cartridge, not the 40". If you would rather fill your own, Tucker sells empty refillable cartridges in the same three sizes.

Black Seal Up, Arrow Shows The Way

Black Seal Up, Arrow Shows The Way

Each cartridge carries a label with its part number and an arrow marked to show which way it loads. Tucker's manuals say to seat a DI canister with its black seal on top, nearest the sump head.

Check the arrow before you close the housing. If a new cartridge shows a TDS reading, Tucker notes that manufacturing residue can register on a meter without spotting the glass.

Got Questions?

Find answers below or contact our support team.

Can I refill a pre-filled cartridge?

No. Tucker sells these as one-time-use cartridges that you replace when the resin is spent. If you want to refill your own, Tucker offers empty refillable cartridges in the 4" x 21", 4" x 30" and 4" x 40" sizes.

Which cartridge fits my system?

Match the cartridge to your housing size. The 4" x 30" fits Tucker's 4060, H2Pro and T-DI systems, and the 4" x 40" is not the 4060 replacement.

How do I know when to replace it?

Check the output with a TDS meter. Tucker's manuals say fresh DI reads 0 ppm, and glass can typically be cleaned spot-free with water up to 10 ppm; once the reading passes that, replace the cartridge.

My new cartridge shows a TDS reading. Is it faulty?

Tucker's manuals say chemical residue from manufacturing can show on a TDS meter but should not spot. Wash a test pane and the reading should clear shortly.

Which way does the cartridge go in?

Follow the load-direction arrow on the label. Tucker's manuals say to install a DI canister with the black seal on top, nearest the sump head.

Can I drink DI water?

No. Water purified by DI resin is non-potable.
