ABSTRACT:
A conduit for a volatile fluid comprises principle lengths of a hard material having a relatively high tensile strength interrupted by rings of a soft ductile material. When the tube is subjected to an impact or excessive forces sufficient to cause rupture, the ductile rings are first drawn to a relatively small diameter, pinching off an inner, resilient seal tube to shut off further flow.
