Buna N O Ring

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 ring.

Buna n also known as nitrile or nbr is a synthetic rubber material. Many compound variations for specific applications. 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. Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene.

As568 standard size buna n o rings are the most widely used o ring material in the world because of low cost good mechanical performance with resistance to water most basic oils lubricants and some fuels many pneumatic hydraulic systems propane natural gas and the default choice for basic applications. Nitrile rubber also known as buna n rubber. Buna n o rings buna n o rings. Buna n o ring assortments also known as quattro seals and x rings these x profile o rings have four points of contact for a better seal in dynamic applications than round profile o rings.

Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications. The least expensive most readily available material. Buna also referred to as nitrile or buna n is an nbr rubber that displays excellent resistance to all petroleum based oils and fuels as well as water various alcohols silicone greases and hydraulic fluids. It s resistance and low compression set make it one of the most used economical elastomer.

Trade names include perbunan nipol krynac and europrene this rubber is unusual in being resistant to oil fuel and other chemicals. Poor resistance to sunlight weathering and ozone. 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. 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.

It offers such other advantages as good tear resistance and non polar solvent resistance. Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets. Buna n o rings aka nitrile nbr in 70 durometer black. Parker buna o rings are recommended for petroleum based oils and fluids mineral oils ethylene glycol base fluids silicone and diester base lubricants air natural gas and water under 150 f 66 c.

A common parker nitrile o ring compound is n0674 black.
