50x72x12 Single Lip Viton Rubber Rotary Shaft SealAcrylonitrile butadiene rubber (NBR) is the material name for nitrile rubber. This material is very good for seals due to its make up. Nitrile rubber can tolerate short term dry running of the sealing lip. The operating temperature range without failure of nitrile rubber is 40 to +100 C. This also offers a special nitrile rubber compound with a temperature range between 55 and +110 C. Please click here for a full in depth look at the range of seals

The rollers work great and fit nicely into my Euphy which turned out I have a early version of which means none of the filters don’t fit my Euphy unfortunately and I hadn’t payed attention to the filters I was looking to get a 2 pack of rollers, the filters look nice though like they would make a great seal with the plastic and seal around them. I won’t buy them again for sure though for obvious reasons. Euphy is so much quieter then my second vacuum that’s a Roomba and she definitely gives her a run for her money and when it dies I will definitely be replacing her with a Euphy.

Very great and durable option.

Style: for Saros 10R / Saros 20 / Qrevo CurvX

These parts are the perfect option when maintaining your robot vacuum. They fit the machine perfectly and are just as if not more durable than the company provided parts. Definitely recommended.
