O-Rings
from Web Seal Inc.

O-rings provide reliable leak-free seals and simple installation. O-rings are an ideal, cost-effective solution for many sealing situations. An O-ring is a donut-shaped ring of molded, flexible material with a round cross-section that can be either solid or hollow. These flexible rings are designed... [See More]

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]
