Buna-N O-Ring-Dash 459 - Pack of 2

Nitrile rubber, also known as NBR or Buna N, is one of the most commonly used sealing elastomers due to its resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds. Acrylonitrile Content: The acrylonitrile (ACN) content of the polymer chains can be varied from 18% to 50%. Lower ACN content gives better low-temperature properties but poorer fuels and polar lubricants. Higher ACN content gives poorer low-temperature properties but improved ...

Buna-N is the most commonly used O-Ring material due to it's strength and durability. Suitable for a broad range of fluids including oils, water, and mild chemicals.

While they are not as strong as other Buna-N O-Rings, Soft Buna-N O-Rings require less force to make an effective seal and conform better to uneven surfaces. They are suitable for a broad range of fluids including oils, water, and mild chemicals.

These O-Rings have an internal lubricant which gives them a low friction surface which makes them easy to install, eliminates the need for adding a lubricant, while reducing drag in moving applications, and eliminating them from sticking to parts in start and stop applications. Excellent strength and resistance to abrasion, oils, petroleum, hydraulic fluids, and water.

Square profile O-Rings require less squeeze to make an effective seal and won't roll or twist in moving applications. Buna-N is the most commonly used O-Ring material due to its strength and durability. It is suitable for a broad range of fluids including oils, water, and mild chemicals.
