  • Patent number: 6367803
    Abstract: A sealing gasket (J) intended to be damped between two pipework connection flanges (5, 9), the said gasket comprising a sealing ring (1) including a rigid metal annular part (11, 13, 18, 16) with which are integral a number of radiating metal lugs (2) capable of being folded along the contour of a support flange. The sealing gasket having to be able to be mounted between flanges of different transverse dimensions, the metal lugs (2) are longer than the corresponding transverse dimension of the largest flanges on which the gasket can be mounted. The lugs can thus be folded to conform with the exact dimension of an assembly flange so that the gasket may be suitably supported centered by the said flange prior to the mutual assembly and tightening of the two flanges.

    Abstract: A tube plug seal has an improved tear line pattern which tears when a mating tube having a circumference smaller than the seal is inserted through the seal. The improved tear line pattern is designed to initially tear where the circumference of the mating tube applies the highest stress. As a result, the improved tear line includes a portion which extends at least partially circumferentially about an axial center point of the seal. More specifically, the circumferential portion of the improved tear line pattern generally aligns with a circumference of the mating tube. In one embodiment the improved tear line pattern is C-shaped.
