Buna N /Nitrile Rubber/NBR O Ring

Nbr Nitrile 70 O-Rings Rubber

NBR is the most commonly used material for o-rings because of its good mechanical properties, its resistance to lubricants and greases and its relatively low cost.

Standard grades of NBR are typically resistant to mineral oil-based lubricants and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 80°C (190ºF).

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 (HFD). NBR also has low resistance to ozone, weathering and aging.
