Abstract

A heating system for a fluid duct such as a water supply pipe utilizes a self-limiting heater cable located within the duct and an insulation around the duct. The cable is inserted through a T-fitting having a scaling member with oppositely directed conical surfaces to engage the fitting and seal against the cable.
