[Powerful Extractor Blade with Tight Seal]-- Constructed from high-strength material, the cross extractor blades rotate at high speed to extract nutrients quickly, helping you make healthy, nutritious smoothies for home or on-the-go consumption. Equipped with a sealing ring, this replacement blade provides a secure, durable seal to prevent leakage, supporting a worry-free blending experience every day. [Extra 2 Gaskets]-- One washer is pre-installed in the blade assembly to ensure a proper seal and prevent leakage. The included accessories are ready to use upon arrival. Two additional gaskets are provided for future replacements. Do not install multiple gaskets at the same time. Each blade should be sealed with only one gasket. Before each use, place the extractor blade onto the cup and twist until tightly secured. [Note]-- Never submerge the blade assembly in water. To clean, twist off the blade, hand wash with warm soapy water, then rinse and dry completely. Do not remove the gasket, as this may permanently damage the blade and cause leakage. For optimal performance, we recommend replacing your NutriBullet bl parts every 6 months or as needed. Color: Grey (random brush color, no specific color selection available). Material: Plastic.
