Title: Mechanical connection for a tubular assembly

Abstract

Disclosed is a mechanical connection assembly for connecting two telescopically related parts together in a fluidtight relation. The system uses snap-in fasteners having flexible barbed tangs which are snapped into receiving holes formed in the parts being attached together. A locking pin can be inserted into a central aperture through the snap-in fastener to secure the fastener in the receiving holes. The system also includes a seal having sealing surfaces at least one of which is formed at an angle inclined relative to a true vertical. a metallic sealing element is interposed between the sealing surfaces. The geometry of the sealing surfaces is capable of compensating for the differential thermal growth rates occurring when the two parts are made from dissimilar metals.
