Buna N O Ring Seal

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

Buna n o ring seal.

Buna is effective to 250 f. Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications. Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f. 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.

However it can effectively seal mechanical objects at low temperatures to 22 f. 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.

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