Abstract
A transition sleeve is inserted into a transition tube of a vacuum system of a vacuum sweeper. The transition sleeve extends the useful life of the transition tube by sacrificially wearing instead of the transition tube. Such wear arises from abrasive grit and other materials swept up by the vacuum sweeper. The transition sleeve is desirably formed using wear-resistant materials. The transition sleeve can include a flange at one end to allow the transition sleeve to be held in the transition tube without using fasteners or bonding agents. A first portion of an interconnection structure is provided at the other end of the transition sleeve and engages with a second portion of the interconnection structure provided at a first end of an extension sleeve to connect the extension sleeve to the transition sleeve. The extension sleeve allows the transition sleeve to be used with transition tubes of varying lengths.
