MIDDIA Precision Zirconia Ceramic Gravity Ball with Silicone Tube Connector

Designed for 360-degree liquid intake systems, the MIDDIA Precision Zirconia Ceramic Gravity Ball with integrated silicone tube connector is a essential counterweight component for baby straw bottles, sippy cups, oral irrigators, and water flossers. Crafted from high-density, pure white zirconia ceramic, this precision-polished sphere weighs down internal silicone suction straws, allowing infants or users to drink or spray water continuously from any angle without sucking air. Unlike metal counterweight balls that can rust or leach heavy metals into warm milk or liquid, high-purity zirconia ceramic is 100% rustproof, lead-free, non-toxic, acid-and-alkali resistant, and chemically inert—guaranteeing complete food safety for infant applications. Engineered with a smooth surface finish and seamless tube fitting, it prevents bacteria accumulation, odor retention, and friction wear. Temperature-resistant and fully sterilizable via high-heat boiling or steam, MIDDIA offers complete OEM/ODM custom ball diameters, connector sizes, low MOQ production, and fast delivery for global bottle and device manufacturers.
