Composite connecting member for hydraulic fluid lines

摘要

A connecting member is disclosed for connecting a hydraulic tube to a base material such as a housing or to another hydraulic tube. The connecting member has an annular body formed from a first material extending a substantial length of the connecting member. The body has an interior surface defining a passageway. The body includes threads on a first portion of the body for connecting to the connecting member of a hydraulic tube and threads on a second portion of the body for connecting the connecting member to the base material or a second hydraulic tube through a coupling nut. A sleeve is made from a second material and extends through the passageway substantially the length of the connecting member. The sleeve has an internal surface and has a pair of ends, wherein each end of the sleeve extends radially outwardly from the sleeve relative to a central longitudinal axis of the sleeve over a respective end of the body. The body may be plastic and the sleeve may be titanium.
