Mudder 6 Pieces Rubber Gasket Replacement Ring Seal White O Ring Compatible with Magic 250w Gasket for Replacement Parts Seal Cups Lids

Worked well in my older magic bullet, fit fine and did not leak.

Just what I needed for the lids and blender blades for my magic bullet blender. They fit and seal very well.

I needed a replacement silicone gasket for my Cooks personal-size blender from JCPenney. This isn't the exact fit. It's a tiny bit bigger, but with patience you can work it in & it does the job of not leaking your smoothie ingredients. I do recommend. 👍👍

After 3 years, our Magic Bullet 250W blender had sprung a leak. The original gasket that came with the blender had a crack in it. Based on product reviews, we purchased these to see whether the problem can be fixed without replacing the blender. The gaskets arrived within a few days and found that one of the gaskets from the package fit perfectly in the blade assembly and the blender works as good as new without any leaks. Not sure how long these gaskets will last. But for now everything is working great!! We have 5 spare gaskets in our arsenal if ever the problem arises again.

Prefect fit

The media could not be loaded.  This gasket is not properly compatible with the Magic Bullet blade base stated in the title or details. This gasket has a raised center peak not shown or detailed in seller's pictures or literature. The gasket is not the proper height making it impossible for the cup to seal. The gasket is the proper diameter and thickness. Instalation was successful. Gasket will not stay in channel if tipped upside down without cup.I may have gotten an improper item from seller.

These fit in the blade part of my magic bullet, but unlike the original ones, they won’t stay in place when you go to open it after using it. Also comes out when you are trying to walk the blade part. I tried to push the gasket into place as best I could but it wasn’t a perfect fit. I thought that maybe it would snug into place by screwing the blade part onto the cup and it seemed to work, but when I opened it after blending something it popped out of the grove again.

This gasket fits a venti Starbucks cold cup perfectly! It's a bit thicker than the original one, and you do have to be a bit careful not to "roll" it when installing. The extra thickness might be a plus; the lid still seals and it can't be overtightened.

Quality of gasket is good
