Abstract

A seal packing made of elastomeric material (9) for a hydraulic apparatus adapted to be inserted in a seat (3) that is recessed into one of two parts (1, 4) between which a seal is to be established and to be pushed elastically into contact with the other part. The packing has a composite structure which is comprised of an elastomeric material (9) in the portions intended to establish the seal and of a rigid or semirigid core (11, 12) material that is at least partly incorporated into the elastomeric material of the packing.
