Buna N O Ring Seal

Buna is effective to 250 f.

Buna n o ring seal.

Get durable buna n and viton o rings from grainger to help tightly seal connections in a wide range of industrial applications. 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. Its versatility makes it an ideal material for o rings seals gaskets and custom molded components for all industries and applications.

They also require less compression to make a seal so they offer a longer service life. Buna n o rings buna n o rings. However it can effectively seal mechanical objects at low temperatures to 22 f. Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f.

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 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.
