ABSTRACT:
A seal or gasket having at least one aperture providing a fluid passageway and intended in use to be clamped by clamping means between surfaces of two parts to be sealed. The seal or gasket comprises conformable elastically-compressible material and relatively-incompressible material bonded therein. The relatively-incompressible material forms an extrusion-limiting barrier which extends at least part-way around the aperture, which is interrupted at intervals by portions of the elastically-compressible material and which is spaced from the aperture by a border portion wholly of the elastically-compressible material.
