What is the difference between a radial rubber o-ring and an axial seal?

Axial seal A cylinder, then the axial direction is the cylinder high, radial and axial direction perpendicular to the direction. In the case of a solid, assuming that a cylinder is placed laterally, the X-axis is the axial direction, and the Y-axis and Z-axis, which are perpendicular to the X-axis, may be referred to as the radial direction. Axial seal is the upper and lower sides of the cylinder rubber seal (that is, two circular face) radial rubber O-ring is the cylinder of the circumferential surface seal (to be a rectangular) For example, Coke bottle cap Can be understood as the axial seal, its plastic foreskin (except the bottom) can be understood as radial rubber O-ring.
