Claim:
1. A joint comprising: a first component having a face and a bore defined by a bore wall, the bore having a tapered opening; a second component; a fastener joining the first component to the second component, the fastener comprising a tapered head and a shaft protruding from the head; and a gasket being substantially disk-shaped before installation, the gasket comprising a fully or partially cured polysulphide sealing material, a fabric impregnated with the sealing material and only a single protrusion which is positioned towards an inner periphery of the gasket and which contains substantially none of the fabric, wherein during assembly of the joint the shaft of the fastener is inserted through the first component and at least partially through the second component, and the sealing material of the gasket engages and is compressed between the head of the fastener and the tapered opening of the first component such that the protrusion engages the tapered opening before the gasket is compressed between the shaft of the fastener and the first component, whereby the sealing material in the protrusion flows along the shaft of the fastener and forms a collar between the shaft of the fastener and the bore wall.
