Nitrile O Ring Application

This popular o ring material family comparison shows basic rubber material family properties and performance plastic properties.

Nitrile o ring application.

O rings are circular sealing elements with circular cross sections and are mainly used in static applications. O ring application guide nitrile rubber. One of the most commonly used elastomers available nitrile o ring cord is a great solution which will give you a versatile material suitable for many uses. Nitrile rubber also known as nbr buna n and acrylonitrile butadiene rubber is a synthetic rubber derived from acrylonitrile acn and butadiene.

O ring compatibility chart offers guidance on chemical resistance and swell for viton o rings ffkm o rings silicone o rings teflon o rings and more. Our o rings are manufactured according to metric and imperial international standards such as as 568b din iso 3601 and jis. The acrylonitrile content varies between 18 and 50 and influences the physical properties of the finished product. O ring material family chemical compatibility temperature resistance and other properties all factor in to o ring material selection for an application.

Viton vs nitrile o rings. Due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of 35 c to 120 c 30 f to 250 f nitrile nbr is the most widely used elastomer in the seal industry today. We can change the formulation of the rubber so that the specifications meet your needs. Trade names include perbunan nipol krynac and europrene this rubber is unusual in being resistant to oil fuel and other chemicals.

This nitrile 70 durometer 70a specifications chart will help you determine if these nitrile material properties will be compatible with your rubber or o ring seal application. O ring material quick reference guide rubber sealing materials. Nbr is used in the automotive and aeronautical industry to make fuel and oil handling hoses seals grommets. These o rings are most commonly used in the refrigeration industry due to excellent resistance to hazardous chemicals like ammonia and coolants like freon 12 14 22 etc.

A higher nitrile content enhances resistance to fuel and oil but elasticity and resistance to compression set is. The elastomer they are made from is cost effective water resistant and weather resistant. Also many military rubber specifications for fuel and oil resistant o rings require nitrile based compounds. O ring compatibility plays a critical role in o ring performance â find the right material for your application and avoid o ring failures.

Neoprene o rings are also known as chloroprene cr o rings and provide good resistance to uv light oxidation and weather applications. Nitrile rubber also known as acrylonitrile butadiene nbr and buna n. As two of the most commonly used elastomers both viton and nitrile o rings have some fantastic properties.
