Buna-N O-rings: - Buna-N (nitrile rubber) is a popular elastomer due to its ability to withstand high temperatures (-40°F to 250°F) and various types of liquids (even some caustic chemicals and solvents). - Buna-N O-rings have good mechanical properties, such as excellent tensile strength and elongation, making them ideal for use in dynamic sealing applications. - Buna-N O-rings are also known for their low compression set, which means that they can maintain their original size and shape even after being compressed for long periods of time. - The O-rings come in various sizes, and their cross-sectional shapes can range from round to square to rectangular. - Buna-N O-rings are typically black, although some manufacturers produce them in other colors for easier differentiation between different sizes or applications. - These O-rings can be used in a wide variety of applications, including pumps, valves, and hydraulic systems, among others.
