Gessi SP00446 25mm Mixer Cartridge | Genuine Replacement for Just Kitchen Mixers

Important Technical Note: If you are removing your old cartridge, it is most likely Grey with a clear stem. The new genuine Gessi replacement (SP00446) is White.

• The O-Ring Confusion: At first glance, the o-rings on the new version appear to be in a different position. Do not be concerned. Gessi has re-engineered this part to ensure a superior seal; this is the correct, official version and it will seat perfectly in your mixer.

• Primary Fit: This 25mm cartridge is the standard replacement for the Gessi Just Kitchen Mixer series.

Genuine Gessi Factory Spare — Made in Italy Gessi kitchen mixers are world-renowned for their minimalist Italian design. Because these taps use a slimline body, they require the specialized 25mm SP00446 cartridge to maintain smooth water control and a leak-free seal.

When to replace this cartridge:

• Dripping Spout: If your Gessi Just mixer continues to drip from the aerator after you have turned it off.

• Leaking Handle: If you notice water pooling at the base of the handle or seeping out from under the lever.

• Stiff Operation: If the joystick or lever has become difficult to move, indicating the internal ceramic discs are worn or calcified.

• Q: The o-rings on my new SP00446 look different to my old one. Will it leak?

  • A: No. Gessi updated the base design to improve longevity. Once the cartridge is tightened down by the brass locking nut, it creates a perfect watertight seal.

• Q: Can I use this in a Gessi Oxy or Rettangolo mixer?

  • A: While many Gessi mixers use 25mm cartridges, this specific SP00446 is primarily designated for the Just range. If you have an Oxy or Rettangolo, please email a photo of your tap to sales@sydneybathroomware.com.au so we can verify the part.

• Q: Is it easy to install?

  • A: Yes, Gessi cartridges are designed for simple replacement. You will need a small Allen key to remove the handle and a shifter to unscrew the locking nut.
