An overmoulded dynamic seal that is overmoulded onto an insert obtained from an elastomeric composition (C) comprising a crosslinked blend (B) of at least:
- (1) one substantially saturated synthetic elastomer;
- and
- (2) a copolymer containing repeating units derived from at least one conjugated diene and at least one α,β-unsaturated nitrile,
- said seal having been subjected to a surface halogenation treatment,
- wherein the insert is composed of a material different from that of the seal and the insert material provides stability to the shape of the seal;
