Product Description


The [DIN 3771" standard for O-rings is produced by the Duetsches Institut fr Normung (German Institute for Standards). The [DIN 3771" specification describes 258 O-rings. Each size is designated by the ID cross-section. Optionally, this designation may be followed by a letter indicating the quality level ([N" - normal quality; [S" - special quality. Subsequent to the letter indicating the quality level, the rubber polymer and IRHD hardness may be specified.


In contrast to the AS 568 A inch system, the nominal and physical dimensions of metric O-rings match precisely. That is, a 1 mm O-ring will have a cross-section of 1 mm. The space that is being filled must be about 10% to 15% smaller than the cross-section of the O-ring in order for O-ring to seal properly.
