HotRod pyrometry sheathsHotRod pyrometry sheaths protect thermocouples in furnace heating control systems. They are made of a durable, erosion-resistant clay-graphite mix with special plasticity properties, which is then extruded into the proper shape. Designed for use in furnaces and other high-temperature environments, these assemblies are supplied with a 0.5-inch (12.7-mm) threaded steel tube for quick and easy attachment to the furnace pyrometry system. 

HotRod sheaths with inner steel tubes are resistant to 1000°C (1832°F) and are typically used for aluminum applications.
