Introduction to Seals and Seal Types A seal is a device that prevents the passage, flow or leakage of a gas or fluid. Seals can be divided into two major categories: 1. Static Seals. Sealing takes place between surfaces that have little or no movement relative to one another. 2. Dynamic Seals. Sealing takes place between surfaces that have relative movement, i.e. the movement of a shaft relative to a housing. There are also seals that fall between these two categories and do not exactly fit into these basic definitions of static or dynamic seals. Some static seals are designed to...

FIGURE 1-2 Standard Closed FIGURE 1-3 Standard Open FIGURE 1-4 Corner Cavity Cavity Segments Typical Cavities Cavity Type There are several cavity types that are considered standard. The cavity is a primary design constraint since it determines the physical envelope for the seal's dimensions. The typical standard cavity types are briefly described below and depicted in Figures 1-2 through 1-5. 1. Standard Closed Cavity. This type of cavity is characterized by a fully enclosed seal area. This type is sometimes referred to as a "U" type cavity. (Figure 1-2) 2. Standard Open Cavity. This type...

variables, including alloy chemistry, processing history, and final heat treatment." (This definition is courtesy of an Inco Alloys International Ins. Paper by D.F. Smith entitled Testing Sensitivity in Low CTE Superalloys dated 3/16/91.) For semi-static seal applications above +1300°F (+704°C), Eaton is researching and developing manufacturing methods for several new high-temperature superalloys. At this time, Eaton successfully utilizes alloys such as Haynes 188® in operating cycles with a maximum temperature of +1600°F (+871°C). Consult Eaton for any applications with operating...

C-Seal Sketch and Description Eaton's C-Seal Performance Capabilities: • Excellent for "rigid" connections where minimal or no axial deflection occurs • Low Leakage rates (10-11 scc/ sec of Helium) • Ultra high vacuum (10-10 Torr) to high pressure (200,000 psi) applications • Intended to deform plastically; little or no springback • Compression load in the range of 100 to 1000 PCI An improvement on the classic metal "O" ring, the C-Seal provides a more flexible, lower load sealing solution which is also pressure energized. Available in three basic orientations (Internal Pressure Face Type,...

Typical load, deflection, or spring-back capabilities are shown in the Load vs. Deflection graph on page 11. It is not suggested, however, that the C-Seal be utilized in a cavity exhibiting this amount of continuous cavity cycling during operation. As a rule, a C-Seal will springback 2% of its free height. Repeated reinstallations or continuous cavity fluctuations in excess of this amount could result in failure of the seal through cyclic fatigue and cracking.
