Cordierite Threaded Tube – High Thermal Shock Resistant Ceramic Spool for Heating Wire

Cordierite Threaded Tube is an industrial insulating ceramic spool specially designed for resistance wire winding. Its precision external thread keeps heating wire neatly arranged and anti-slip, effectively eliminating short-circuit risks. The cordierite material endows the tube with outstanding thermal shock resistance, with no cracking under repeated hot-cold cycles, while maintaining stable insulation under high-temperature operating conditions. Widely applied in industrial furnaces, tubular heating elements, and various radiant heaters. Custom outer diameter, length, and thread pitch are available for different power ratings, reducing equipment failure rates and extending service life.
