<p>The present disclosure relates to seals and sealing arrangements, especially those used in wireline valves. The seal comprises an elastomeric seal body with a sealing surface, a plurality of generally planar inserts embedded within the elastomeric seal body adjacent the sealing surface, and having elastomeric seal material disposed between the plurality of generally planar inserts. The generally planar inserts may have a slightly wedge shape and may be embedded into the elastomeric seal body in a generally fan-shaped orientation. They may be orientated such that upon contacting a substantially tubular shaped body to be sealed around and the subsequent deformation of the seal body about said substantially tubular shaped body, the plurality of generally planar inserts become orientated such that they extend radially from the substantially tubular shaped body.
