Black Brown Green White NBR Abrasion Resistance Nitrile Rubber Strip Sealing O Ring Cord
O Ring cord/ Rubber strip
Function of the rubber o ring cord
Rubber O-ring cords is a commonly used name for extruded sections made of homogenous rubber.
We offer rubber cords in versions with round and square profiles. The selection of the right profile
of the sealing cord depends on the application. Rubber sealing cords are made by the extrusion and
free vulcanization of rubber mixtures.

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.
O Ring cord/ Rubber strip applications:
1) The primary application for cords is as the basic material for joined O-rings.
2) They are similar to the O-ring in the way they are handled and applied.
3) They are used as static seals, e.g.
4) for sealing larger pipe unions and as cover seals in container construction.
5) Cords are frequently used for on-site repairs, being joined together to provide the "customized"
dimensions.
