Abstract
Apparatus and method for applying thermal energy to a sealing member. Electrical current is applied to a heating assembly to generate thermal energy, and a heat conductor transfers the generated thermal energy to a seal member adjacent a housing. The heating assembly is configured to substantially prevent a magnetic field generated by the applied electrical current from extending to the housing.
