Ceramic Strip Heaters can also be terminated with convoluted conduit

Convoluted Conduit: Convoluted conduit is commonly used with Gala style heaters. Unlike standard S/S conduit, convoluted conduit is sealed and provides excellent moisture protection.  This also forms a positive seal against contamination entering the heater.  The convoluted conduit is brazed directly to the heater forming a strong junction.
