Title:
FERRULE SEAL
Document Type and Number:
WIPO Patent Application WO2001073338
Kind Code:
A9
Abstract:
Seal apparatus for sealing about a fracturable tube, includes a ferrule (30) with an axial bore (32) to receive a tube, and a longitudinally bored outer component (20) having a cavity (24) to co-axially receive the ferrule. The ferrule has an external surface (35) that tapers to a tip region (36) defining one axial end of the ferrule. The cavity has a peripheral wall (25) that tapers with a steeper taper angle than the tapered surface of the ferrule, to a cross section smaller than the tip of the ferrule. The cross-section of the tip region and the relative taper angles and hardnesses of the tapered surface and the tapered wall are selected whereby, on relatively drawing the tapered wall of the outer component cavity onto the tapered surface of the ferrule, the tip region is deformed for sealing gripping a protectively coated fracturable tube traversing the bore of the ferrule, without fracturing the tube.
