140x180x12 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

I love this company for all my supplement needs. My only complaint about the magnesium supplement is that the capsules are pretty large. If you have a problem swallowing pills/capsules you may have a bit of trouble swallowing these. However, I’ve never had magnesium that was easy to swallow. Most of Pure Supplements are small and very easy to swallow. The magnesium is the exception. All magnesium pills are large.
