Rated 3 out of 5 by from It wasn't the ring... Oster blender worked great for a couple of years. I bought replacement parts to service my blender and hopefully get s few more years out of it. Unfortunately soon after replacing the parts, I realized the connecting mechanism between the base and the container was stripped or worn out and I don't think this is a part that can be easily fixed.

Rated 5 out of 5 by from Exactly what I needed I was heartbroken when I lost the rubber ring for my blender. I make all my food for my 8 month son with it and didn't like the idea of shelling out money for a new blender when mine worked fine. Went on the webpage and found exactly what I needed! Price was great and came quickly!! Very happy

Rated 4 out of 5 by from Relieved to have 2 new gaskets for my blender Ihad been looking for these gaskets for almost 10 years. I was considering buying a new blender as my old gasket was not clean. I finally thought of searching online for the gaskets....i am very happy to have them..i havebeen blending up a new shake recipe each day. How rewarding!

Rated 1 out of 5 by from Wrong part. I bought the blender over a month ago and the sealing ring wasn't anywhere to be found so I ordered one from your site that stated it fits most models. Unfortunately it didn't fit mine at all. It was way too small. Now I haven't had a working blender in over a month.

Rated 5 out of 5 by from Great customer support My wife and I love our blender. We use it so much we have worn some parts out! We love that parts are still available for blenders so we can repair our blender instead of replacing it and having a perfectly good product end up in the landfill. Thank you Oster!

Rated 5 out of 5 by from Great service I got surprised that I was able to order part for my Oster Blender. I thought I had to put it in the garbage but no, thanks to this site, my blender got fixed and I'm very happy with the parts quality and the whole process from ordering to receiving the shipment.

Rated 4 out of 5 by from Oster Sealing Ring My Oster blender has always been in perfect working order but the sealing ring of course wore out after 10 years + of usage. So glad that the rings can be ordered on line separately from Oster. Ring is exactly as described and works perfectly.

Rated 5 out of 5 by from Works great I never thought my Oster blender could be repaired. I love this blender and am so happy now its fixed. The price for the parts was wonderful. In this throw away world, its good to know companies like yours offer alternatives.

Rated 3 out of 5 by from Replaced after first use! Kinda upset that I had to replace the original seal after only using my blender once! Glad it came with 2 in case it breaks as easy as the first time but praying it won't! And seems to he holding better then the original!

Rated 5 out of 5 by from easy, quick, reasonable I was very happy to find a blender part and sealing rings on line. No searching, calling, driving. It arrived promptly and while my order was too small to receive free shipping, I felt it well worth the convenience.

Rated 3 out of 5 by from Product ok I bought the seals for my blender. They arrived quickly. They fit great however the rings were stuck to the colored cardboard and I can not get the rings clean. I have soaked and scrubed them with no luck.

Rated 5 out of 5 by from Came quickly, fits well, perfect replacement! I ruined my past ring by improperly screwing on the blade assembly and running my blender. These rings were cheap, arrived quickly and allowed me to go back to my smoothies! Would definitely order again!

Rated 5 out of 5 by from Fit perfectly However, the packaging was not great: the blue wrapping cardboard stucked to the rings and left on them blue stains that I could not remove. There is definitely room for improvement on that point.

Rated 5 out of 5 by from Exactly what I needed. My blender is approximately 35 years old and still going strong. I was impressed that the company has maintained design dimensions and that the current rings fit. Thank you Oster!

Rated 5 out of 5 by from Quick Delivery! I have not used the sealing rings yet, so can not review them. I will say that the delivery time was quick. I'm sure that the rings will work fine, as I have used them in the past.

Rated 3 out of 5 by from Unreasonably difficult to find replacement parts When I asked how to get this replacement part for my blender, I was given a copy and paste answer to visit listed retailers. Once my question was answered, I was showed hundreds of people asking the exact same question. Maybe put that information right on the part's page, save yourself some copy/paste time? Of the listed retailers in Canada, the only one that actually offers replacement parts is There is no official seller, so you have to go through a quagmire of Chinese knock-offs, and make sure to read every review, because most of them are garbage that doesn't last a few months, and has no return policy. Oster really should point us to an actual certified reseller of the parts, if they're not going to offer them directly, so we don't have to spend all this time and wasted money on knock-off garbage. For as much as I like my blender, the service and support of this company really need to be sorted out. I did eventually find a seller who had more positive reviews. The price was much more than I think two rubber sealing rings should ever cost. It's been about a month and they have yet to arrive.

Rated 5 out of 5 by from Ring toss We accidentally threw out the ring needed for our blender. Panic! Great thing we could order them online. A perfect fit, and we have a spare in case!

Rated 5 out of 5 by from Excellent and fast shipping service. I recently bought a package of 2 sealing rings for my 55 year old Osterizer blender and it is like new again. I'm so happy that I found your site.

Rated 5 out of 5 by from Oster Sealing Rings Had the rings shipped to me about three weeks ago. I was so happy to find them on your website as it was past time to replace the one I had.

Rated 3 out of 5 by from Parts fine, shipping not so much The parts were fine, and shipping time was fine. However, the part was about $5, the shipping $15. Oster should work on reducing this cost.
