Self-sealing flexible metal hose

摘要

A self-sealing flexible metal hose includes a band adapted for winding on conventional winding equipment. The band includes receiver and insert assemblies adapted for interlocking with adjacent windings or turns of the band. A sealing flange provides continuous contacts and is urged into sealing engagement with the band by exhaust gas pressure within the hose bore. Alternative embodiments include different configurations of the flanges and legs which form the contacts, and accommodate packing material for greater sealing performance.
