Seal Types

Further discussion in this section and in the remainder of this ehandbook is based on specific types of O-rings and special applications. Definitions of commonly used terms connected with O-ring seals are provided in the glossary. These terms are common to the sealing industry.

Comparison of Common Seal Types

A number of common seal types, T-Seals, U-Cups, V-Packing and other devices, have been, and are still used for both dynamic and static seals. When compared with an O-ring, these other seal types may show one or more design disadvantages which might be overcome by use of an O-ring. As an aid in assessing the relative merits of an O-ring, the table below lists several of the important factors that must be considered in the selection of any effective seal geometry.
