Find O-Ring Sizes Across Standards

Look up O-ring dimensions across AS568, Parker 5-XXX, JIS B2401, BS 4518, DIN 3771 and ISO 6149 / SAE J2244. Toggle standards on or off, switch between inches and millimeters, and search by size designation (e.g. 214, P10, 5-578).

Don't know the part number? Use Find by dimension to match any combination of inside diameter, outside diameter and cross-section width within a tolerance window. Select any row to see a scaled cross-section and the full inch/mm dimensions.
