rubber o ring sizes
Rubber O ring sizes represent a crucial component in modern engineering and manufacturing, offering versatile sealing solutions across numerous applications. These circular elastomeric seals come in standardized dimensions, typically defined by their inner diameter, cross-section thickness, and material composition. The sizing system follows international standards, including AS568, ISO 3601, and BS 4518, ensuring consistency and interchangeability across different manufacturers. The most common sizes range from microscopic dimensions of 1mm to large industrial sizes exceeding 1000mm in diameter. Each size category serves specific purposes, from precision instruments to heavy machinery. The cross-sectional thickness, equally important, varies from 0.07 inches to 0.275 inches in standard configurations. Modern manufacturing techniques ensure precise dimensional accuracy, with tolerances often maintained within ±0.001 inches. These O rings function by creating a compression seal when installed in a groove, with their effectiveness directly related to proper size selection and installation. The wide range of available sizes makes them suitable for static, dynamic, and specialized sealing applications across industries like automotive, aerospace, plumbing, and medical equipment manufacturing.
