Abstract
A seal assembly for a bypass valve in a well tool such as a packer has a tubular seal carrier with a pair of annular seal elements mounted in a longitudinally spaced relation about the outer periphery thereof. The annular seal elements are anchored in separate grooves around the exterior of the seal carrier such that they are prevented from being dislodged by fluid pressure. Another seal can be provided around the interior of the seal carrier to seal between this seal carrier and a well tool or packer mandrel.
