Buna O Rings

Fda and nsf61 compliant o rings feature a round cross section and medium hardness.

Buna o rings.

Buna n o rings 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. Nitrile butadiene rubber nbr is a family of unsaturated copolymers of 2 propenenitrile and various butadiene monomers 1 2 butadiene and 1 3 butadiene the additives used to accomplish this are not always compatible with buna n and has resulted in the auto industry upgrading o rings to viton elastomers. They offer low temperature flexibility with low gas permeability and are resistant to ozone weather water steam. Ketones mek halogenated hydrocarbons auto aircraft brake fluids strong acids sunlight ozone weathering.

Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications. Buna is a widely used elastomeric material known for its tensile strength and high fuel and oil resistant properties. 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. Get durable buna n and viton o rings from grainger to help tightly seal connections in a wide range of industrial applications.

Buna n rings with durometer 70 shore a can offer hood physical properties and provide excellent resistance to petroleum products. Properties of buna o rings. 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. 35 f to 250 f specialty.

Buna o rings are used as face to face and shaft seals and allow rotary and linear movement. Each features a round cross section. Silicone greases oils water petroleum oils fuels ethylene glycol fluids. Buna n also known as nitrile or nbr is a synthetic rubber material.

Nitrile o rings have good tear and abrasion resistance with operating temperatures from 30 f to 250f 57 c to 121 c which can be higher with special compounds. Buna n nitrile order o rings online. 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.
