Nitrile (NBR) Gasket 

Nitrile rubber gasket material for petroleum based solvents, lubricants and industrial sealing service

Nitrile Rubber has very good resistance to petroleum-based Solvents and Lubricants. Standard grades of NBR are typically resistant to mineral oil-based lubricant and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 80°C.

NBR is generally not resistant to aromatic and chlorinated hydrocarbons, fuels with a high aromatic content, polar solvents, glycol-based brake fluids and non-flammable hydraulic fluids. NBR also has low resistance to ozone, weathering and aging, but in many applications this has no negative effect.
