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

Piston Gland Seals: The ID of the o-ring should be smaller than the OD of the gland so the installed o-ring is always slightly stretched (max 5%) · Rod Gland 

Second: Pick the series O-ring desired, based on the thickness of the flange available to cut the groove depth desired. (I-244) Third: Check the swell characteristics of the fluid on the rubber to determine whether the normal or high swell chart will be used for dimensions of the O-ring groove. (In this case 0-15% or normal swell Chart I)

Through our extensive research we believe that these O-ring groove dimensions and fit details will provide the optimum O-ring compression squeeze for your seal to prevent O-ring leaks. Based on the cross section (CS) of your O-ring, you will choose the corresponding O-ring groove depth and O-ring groove width dimensions.

O-Ring Calculator. The online O-Ring Calculator offers engineers and professionals a quick and easy way to calculate O-Ring dimensions and the appropriate housing layout in accordance with the international O-Ring standard ISO 3601. By simply entering installation specifications for an application, it recommends O-Ring sizes, housing layout and

The proper o-ring size is a fundamental aspect of proper o-ring performance. Whether your application conforms to U.S., Japanese JIS, British BS, or Common Metric sizing for o-rings, these o-ring size charts will help you locate the right o-ring size. If the o-ring, quad-ring, x-ring or square-ring you need doesn't fit these standards, custom

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).
