The TriMAXX™ Coiled 7-Way Sealed System from Sloan Transportation Products is now available for the heavy duty market. Sloan's sealed plug, when combined with the receptacle, provides the industry's most secure and contaminant-free connection between tractor and trailer. The TriMAXX™ System helps minimize truck downtime with the industry's first integrated plug-face gasket that creates a positive seal to the receptacle, stopping corrosion from reaching the terminals.
