Abstract
An annular or linear seal having a substantially K-shaped cross section. The seal with cleft seating surface provides a two-way pressure barrier when it is installed in a groove having a cross section of 'sigma' shape, wherein the flat side of the K-shaped cross section of the seal with cleft seating surface is in contact with an interface in a sliding relationship and the concave side opposite to the flat side of K-shaped cross section seats on the convex bottom of the groove with a 'sigma'-shaped cross section. Of course, the seal with cleft seating surface may be used as a static seal disposed intermediate two surfaces including no movement therebetween.
