[Powerful Extractor Blade with Tight Seal]-- Constructed from high-strength material, the cross extractor blade rotates at high speed to efficiently extract nutrients in minutes, helping you create healthy, nutritious smoothies for home or on-the-go consumption. Equipped with a sealing ring, this replacement blade offers improved sealing performance, enhanced durability, and leak resistance, supporting a worry-free blending experience for a healthier lifestyle. [Extra 2 Gaskets]-- One washer is pre-installed in the blade assembly to ensure a secure seal and prevent leakage. The accessory is ready to use upon arrival. Two additional gaskets are included for future replacements. Do not install multiple gaskets at once—only one gasket should be used per blade. Before each use, place the extractor blade onto the cup and twist firmly until tightly sealed. [Note]-- Never submerge the blade assembly in water. To clean, simply twist off the blade, hand wash with warm soapy water, and rinse thoroughly. Dry the blade completely after washing. Do not remove the gasket, as this may cause permanent damage and lead to leakage. It is recommended to replace the blender blade every 6 months or as needed to maintain optimal performance.
