Abstract

A sealing assembly for attaching pliable tubes to rigid connecting members, for high pressure, low temperature service, which seals by compressing a sealing wafer around the pliable tubes. The pliable tubes pass through holes in the sealing wafer. As the wafer seal is axially compressed, the wafer seal is restrained against radial expansion, thereby exerting an inward radial pressure on the holes through the wafer seal to cause an hermetic seal between the wafer seal and the pliable tubes. A swage bushing can be used, with swage tubes that are swaged onto the pliable tubes by a swage clamp, for the purpose of axially restraining the pliable tubes.
