Refractory Thermocouple Assemblies Refractory fiber and cement laminate tubes have a maximum service temperature of 1500°F (815°C). The tubes come complete with a 20 gauge Type K thermocouple and 36” of lead wire installed. This eliminates the need to buy them separately. The tips of the tubes are made from silicon carbide to increase the response time. Refractory tubes are used in molten Zinc and Aluminum die casting applications. These refractory tubes will not shatter like ceramic tubes. They also will not contaminate the molten metal as a stain-
