ABSTRACT:
A composite elastomeric member for use in well apparatus and adapted to be supported by a well element having a surface for engagement with a surface of a well component, the composite member including a preshaped, reinforcing, mesh-like lamina of selected mesh density carried by and embedded in the member and extending laterally and longitudinally with respect to an axis of the body member, the lamina being bonded to the elastomeric body member and located in a selected zone of the body member to support the sealing surface against unwanted flow of elastomeric material caused by well or well apparatus pressure conditions. The preshaped wire mesh lamina may be stressed independently of the elastomeric material of the body member, may be partially exposed at said sealing surface, and may be of stainless steel.
