These replacement sealing rings are a lifesaver for keeping your ice cream machine running smoothly! The package includes everything you need - 10 small O-rings, 2 large O-rings, 2 rod beater sealing tubes, and 1 valve rod sealing tube. The food-grade material is completely colorless and odorless, so you don't have to worry about any weird tastes transferring to your ice cream. I used these to replace the worn-out seals on my YIKAFU machine, and the difference was immediate - no more leaks and much better freezing performance. The quality is impressive - they're durable, don't stretch out easily, and create a perfect seal every time. What's great is that they're compatible with most popular ice cream machine brands including YIKAFU, COOCO, Xu Zhong, and Hao Bo. Installation was straightforward, and having the full set meant I could replace all the aging seals at once rather than dealing with gradual failures. These are perfect for when your original seals become loose, yellowed, cracked, or just generally worn out from regular use. The value is excellent compared to buying manufacturer parts, and the performance is just as good. Whether you're maintaining a commercial machine or just keeping your home ice cream maker in top shape, these sealing rings deliver reliable performance and peace of mind. Definitely keep a set on hand for when your machine needs some TLC!
