Replacement cartridge ring for the Zen Water Vitality 4 Gallon Countertop System. For placement on top of the Vitality middle ring as shown in photo. The cartridge ring holds the 5-Stage Mineral Filter Cartridge in place.
This cartridge ring has a unique indentation (as shown in the 3rd photo) on the thread. This indentation is not a defect but rather a feature that prevents vacuum effect and is not a defect in the ring.
