METRIC “O” RINGS
BUNA-N
Buna-N (Nitrile)
The most common nitrile copolymer blend is the
compound known as Buna-N. Possessing very good
resistance to petroleum based hydraulic oils, Buna-N
also works well with fuels such as diesel or gasoline.
Nitrile seals have a good resistance to compression
set, but their flexibility suffers somewhat in the lower
temperature range. Seals made from this material
have a low resistance to ozone and must be stored
carefully in most environments. Working temperatures
are -40° to +240° F.
