Abstract

Gaskets are obtained by cutting sections from a tubular moulding having an expanded or foamed core and an integral impermeable skin. The surface has radial corrugations which promote uniform axial compression of segments cut from the moulding. Longitudinal (skinned) passages through the foam provide anchorage bolt holes in the producer gaskets. Polyurethane or PVC foam mouldings are used.
