nominal cross section O-Rings. Until now, O-Ring standards have left a gap between the 1/8" and 3/16" nominal cross sections. In de- signing this new group of O-Rings, we left spacing in the part numbers to allow us to add additional sizes should they be required. Please contact us if you are looking for a size not shown in the 5/32' group.

on O-ring drive belts and their application will be found in O-Ring Applications, Section III. 1.2 What is an O-Ring Seal? An O-ring seal is used to prevent the loss of a fluid or gas. The seal assembly consists of an elastomer O-ring and a gland. An O-ring is a circular cross-section ring molded from rubber (Figure 1-1).

THE O-RING EXAMPLE Throughout this guide, the o-ring is used as an example in our discussion of seal design principles. We have made this choice for these reasons: 1. It is the most common and most widely known type of seal in use today. 2. It is used in all types of applications and by a broad range of industries. 3. In most new designs, the o

If the friction of the moving metal sur-face across the O-ring is in the same direction as the direction of the pres-sure, the O-ring will be dragged into the clearance gap more readily and thus extrude at about 35% of the
