Buna N O Ring Seal

Viton seals are rendered ineffective at temperatures below 5 f with the material becoming hard and inflexible.

Buna n o ring seal.

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. Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f. They also require less compression to make a seal so they offer a longer service life. Get durable buna n and viton o rings from grainger to help tightly seal connections in a wide range of industrial applications.

Buna n o rings buna n o rings. Buna n also known as nitrile or nbr is a synthetic rubber material. Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications. 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.

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. Buna is effective to 250 f.
