NBR Rubber Features:
Nitrile rubber (NBR, Buna-N) provides excellent resistance to
petroleum oils as well as mineral and vegetable
oil. Nitrile rubber also offers strong resistance to heat aging -
often a key advantage over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump
diaphragms, aircraft hoses, seals and gaskets as well
as oil-lined tubing. Due to its versatility, nitrile is used in
applications involving not only oil and fuel resistance,
but those applications requiring resistance to heat, abrasion,
water, and gas permeability.
Different elastomers have different compatibility with various
chemical elements and their characteristics. See the
table below for more material knowledge to order the most
cost-effective o-rings from us.
