40x55x7 Single 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

Love the fact that it's made in America, the packaging is nice, and the ingredients are good. With that being said, the product itself isn't set well. You need to be able to put it on without so much going on your lips. Maybe more beeswax...not sure but something to make it go on smooth not gritty and not get all over the place. I tried putting it in the fridge to harden it up with no luck.

Not for me

For me… it was way too greasy,spread on to my face around mouth. But worst of all it gave my lips a slight allergic reaction. I’m a fan of beef tallow I use it frequently but my normal tallow was not in stock so I tried this one. It wasn’t for me unfortunately.
