O-RING SIZE LIST INFORMATION

O-rings are the most commonly used and widely available rubber sealing rings in the market. Various nations and organizations have developed o-ring sizing standards that are now used worldwide. Popular o-ring size standards include USA's AS568 o-ring size chart, the UK's BS 1806 o-ring sizing chart, and Japan's JIS B 2401 o-ring size list. Metric o-rings and custom size o-rings are often used when a standard o-ring size will not fit an application or existing hardware. X-rings and Square-rings Marco Rubber offers custom o-rings and non-standard o-rings in most materials with no tooling fees or setup fees. If you don't see the size you need listed in a standard or metric o-ring size chart then please contact us or request a quote.

X-RING AND SQUARE-RING SIZE LIST INFORMATION

X-rings and Square Rings are widely available in standard USA AS-568 sizes. Tooling for metric x-rings, metric Quad-Ring® Seals, and metric Square Rings is less common than metric o-ring tooling. Marco Rubber offers custom x-rings, custom square rings, non-standard x-rings, and non-standard square rings in most materials with no tooling fees or setup fees. If you don't see the size you need listed in a standard x-ring size chart or standard square ring size chart then please contact us or request a quote.
