Abstract
A sealing ring provides a fluid seal between a first flange and a second flange. The sealing ring forms a tubular element and includes a tapering wall member defining an interior funnel-shaped through-going opening extending axially and tapering from a proximal end to a distal end. The tapering wall member is made from a resilient material proving an axial deflection of the tapering wall member when exposed to an axial force.
