Blender Sealing Ring Gaskets O-Ring Gasket Seal O-Gasket Rubber Compatible with Oster and Osterizer Blender Models (4 Pack)

Gaskets fit perfectly.

These came earlier than expected and work perfectly in my Oster blender. When I contacted Oster about getting a replacement gasket first they wanted to know what model was the blender and style # which uou can't find on the machine where they tell you it is, then they want to know what happened to break it, what speed the blender was on, what i was trying to blend, if it was in the right place, dah, and then send a picture, receipt of purchase and so on! Best part of all that us I got the blender as a gift and hadn't opened it for a few months and right away after the first time using it the gasket split like it was super dried out. Yet after all that crap they say they don't have them and give me the website to some crazy place where the cost of one gasket is ridiculous and then the cost of Shipping! These fit perfectly, and I now have 4! Have used it almost every day since and it still doesn't feel like the original one (super dry) that I got with the blender that split immediately! Don't 2nd guess yourself! Order them you'll be so glad you did! Great purchase!

Fits my Oster classic. Recommend replacing seal regularly, ruined batch of mayonnaise because old seal came loose and got chopped up. Cost of seals are cheap compared to lost ingredients. Handy to have extras on hand, used one to seal leaky hummingbird feeder.

Exactly what I needed

Took mixer our of storage, the rings I got from grocery/sundries store were 2mm larger and did not fit in existing kit. Ordered these, dropped two into my blender cups where they fit just fine. Two spares in the cabinet. I trust these will last me a good while.
