ABSTRACT:
An O-ring seal for sealing two concentric members is disclosed. A hollow ring made from an elastomeric material is provided with a central liquid core. Temperature changes which normally result in a contraction in the elastomer material are compensated by the expansion of the liquid core. The O-ring maintains a sealed condition between the two members over a wider temperature range.
