If your Oster juicer's reamer cone is worn out or broken, this Univen replacement is exactly what you need to get back to fresh-squeezed juices! This white cone fits perfectly with Oster juicer models 4100, 368-04, 368-06, and the Kitchen Center juicer attachment model 952-08B. The 1/2 inch hexagon shaft matches the original specifications, so installation is straightforward - just slide it onto your juicer's drive shaft. Univen makes quality replacement parts that are built to last, so you don't have to buy a whole new juicer over one broken component. The cone design efficiently extracts juice from oranges, lemons, limes, and other citrus fruits without wasting precious juice. Having a fresh, sharp reamer makes a huge difference in how much juice you get from each fruit compared to worn-out cones. Whether you're making morning orange juice, lemonade for summer, or fresh lime for cocktails, this replacement part restores your juicer to like-new performance. Much more affordable than replacing your entire juicer, and the quality matches or exceeds the original part. If your current cone is slipping, not gripping fruit properly, or just not extracting efficiently anymore, this replacement will make your juicer work like new again. Your fresh-squeezed juice routine doesn't have to end because of one broken part!
