Buna O Rings

Buna n also known as nitrile or nbr is a synthetic rubber material.

Buna o rings.

35 f to 250 f specialty. Buna o rings are used in applications for engines gearboxes aircraft pumps and water. It combines resistance with low compression set and high abrasion resistance to make it the seal industry s most widely used economical elastomer. 70 f to 275 f.

Buna n nitrile order o rings online. Buna n o rings buna n o rings. 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. 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.

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. Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications. Each features a round cross section. Silicone greases oils water petroleum oils fuels ethylene glycol fluids.

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. 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. Buna n rings with durometer 70 shore a can offer hood physical properties and provide excellent resistance to petroleum products.

They offer low temperature flexibility with low gas permeability and are resistant to ozone weather water steam. Properties of buna o rings. Buna also referred to as nitrile or buna n is an. Fda and nsf61 compliant o rings feature a round cross section and medium hardness.

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. Buna is a widely used elastomeric material known for its tensile strength and high fuel and oil resistant properties. Buna n and viton o rings can be used for sealing valves faucets flanges engines and more.
