30x52x7 Double Lip Nitrile 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

Pros- lightweight, small, very accurate, easy to clean, timer included. Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some! This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them. That’s it that’s all

Decent 3oz measurer

I like it, it works. However it is a bit heavy on the handle side. You think somebody like maestri house would get it correct. Could have used heavier metal on the measuring cup. Anyways I keep it it's nice.
