ABSTRACT:
In a tube coupling a resilient sealing boot is disposed between facing frusto-conical sealing surfaces to prevent fluid flow therebetween. A first tube is provided an external frusto-conical sealing surface and an outer cylindrical surface adjoining the external sealing surface, and a second tube is provided an internal frusto-conical sealing surface within an end thereof. The sealing boot is preferably formed entirely of a flexible graphite material to include a cylindrical collar that fits over the outer cylindrical surface of the first tube, and a skirt having one or more integral O-rings which engage one or both of the facing frusto-conical sealing surfaces as the ends of the first and second tubes are drawn together.
