Buna n nbr nitrile.
Buna o ring material.
Nitrile is unique among synthetic rubbers in that it is generally resistant to chemicals such as oil and fuel among other substances such as mineral and vegetable oils diluted acids.
Standard durometer is 70.
O ring material quick reference guide rubber sealing materials.
Viton is the choice over buna for high temperature applications.
Nitrile elastomers are copolymers of acrylonitrile and butadiene.
This popular o ring material family comparison shows basic rubber material family properties and performance plastic properties.

Buna nitrile o ring material description.
Buna n also known as nitrile or nbr is a synthetic rubber material.
O ring and rubber seal materials.
Has an operational temperature range of 40 f to 250 f 40 c to 121 c and a hardness range of 40 90 durometer.
O rings made from nitrile are typically used for general sealing purposes which includes sealing of hydraulic fluids petroleum oils water and so on.
Buna n o rings also referred to as nbr o rings and nitrile o rings are the most widely used o ring material in the word because of low cost good mechanical performance with resistance to water most basic oils lubricants and some fuels many pneumatic hydraulic systems and the default choice for basic applications.
A synthetic rubber with excellent oil resistance and fair to good chemical resistance.
Nitrile buna n o ring the material nitrile also known as buna n or acrylonitrile butadiene rubber functions at a temperature range of between 65 f and 300 f.
O rings are an integral component in most industrial and mechanical systems.
Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f.
Because o ring material selection is driven by an industrial or mechanical system that system will define which material is best suited to fulfill the application requirements of the o ring.
Buna n sometimes shortened to just buna is a trade name for nitrile rubber known internationally as nbr.
