Harnessflex specialty conduit systems from Thomas & Betts provide comprehensive wiring protection for critical electrical and electronic wiring assemblies in heavy-duty commercial vehicle applications, including bus, truck, agricultural vehicle, and heavy machinery. The product line includes conduit, hinged fittings, connector interfaces, and sealed fittings. Components, used individually or in combination, provide protection from not only moisture but also mechanical abrasion and corrosive salts. Commercial vehicles are often subjected to water and moisture, so protection of the entire wire harness improves vehicle reliability, according to the company. Combining a full range of slit and unslit conduit, fittings, and connectors, the Harnessflex systems also offers custom connector interfaces.
