| Detailed Description: |
You probably have run across someone calling for a dash number like -012 or –213 when they reference an O-ring. These "Dash Numbers" are actually from Aerospace Standard AS568B that assigns a dash number and tolerances to a size of o-ring, I.D. X C/S. AS568B size O-rings, commonly referred to as standard size O-Ring, are probably the most common used here in the US and pretty much found everywhere. But, it doesn't stop here, there are several other size standards throughout the world such as DIN3771, British Standard (BS), Japanese Industrial Sizes (JIS-B-2401) and many others.. |
