ABSTRACT:
A low leakage seal for separating two environments and contacting a component surface is provided. The seal includes a base and an annular rib. The annular rib is coupled to and extends from the base. The annular rib includes at least one contact surface configured to contact the component surface having a plurality of angularly cut radial grooves formed therein. The annular rib flexes and pressure energizes in the presence of a pressure differential between the two environments.
