O-Rings -- MA7
from Hi-Tech Seals, Inc.

The U.S. Air Force first regulated O-ring sizing under the system AS-568. A properly designed O-ring groove allows the O-ring to be squeezed diametrically out-of-round even before the application of pressure. The O-ring is the most widely adopted seal in history because of its simplicity, low cost,... [See More]
