What’s a Face Seal?

Face seals are used to connect two objects and prevent leakage of liquids or gases. They come in various types and sizes, including O-rings, C-rings, and E-rings. They improve efficiency and safety, and require periodic maintenance to ensure proper function.

Face seals are simple devices that are used to bridge the slight gap that can occur between two ends, effectively creating a connection that allows liquids or gases to flow without any incidence of leakage. A face seal normally fills the small space found with the grooves or in the cavity of some type of flange. There are several types of face seals, including O-rings, C-rings, and E-rings.

The primary purpose of a face seal is to establish a solid connection between two objects, typically by filling any slight gaps or openings that may remain when the two ends are placed together. By adding sealing to the process, any small gaps that may be present are effectively blocked or closed, a feature that will often improve the efficiency of the machinery or equipment involved, as well as allow the device to operate with a greater degree of safety. Since the type of seal required varies in size and shape, there are seals created for any situation.

A face seal can be used to ensure that liquids or gases can pass through a system without apparent leaks at joints or other areas where sections of components are joined. By acting as a buffer to connect the two ends, the gasket helps reduce the loss of what is carried through the system. When properly installed, the gasket also helps maintain an acceptable pressure level within the enclosure, which can often be critical to device operation.

In addition to helping equipment maintain a certain level of efficiency, the use of a face seal can also be seen as a safety measure. Since the seals retain everything that is transferred through the contained system, the potential for human operators to be adversely affected by such substances is minimized. Worn seals that no longer contain the flow of certain liquids or gases will allow for some degree of leakage and could pose a safety risk to anyone working in the immediate vicinity. For this reason, it is not uncommon for periodic maintenance of production machinery to include periodic inspection and replacement of gaskets, O-rings and other types of face seals in an effort to not only keep the equipment running at peak efficiency but also to keep the work environment relatively safe for employees.
