The X-ring, named for its four-lobed cross-section profile, brings some unique features to the seal designer’s table.
The four-lobed design provides twice the sealing surface of an O-ring and may be used in the same sized O-ring groove. With more sealing surface, less radial squeeze is required to provide an effective seal. Lower squeeze yields lower friction and wear, prolonging seal life. The area between the lobes also acts as a lubricant reservoir, further lowering friction and enabling smoother startups.
