MIDDIA High-Purity Alumina Ceramic Thermocouple Protection Tubes and Insulating Sleeves (Item No. AC11)

Engineered for high-temperature industrial furnaces, thermocouple sensor insulation, semiconductor thermal processing, and corrosive chemical environments, MIDDIA AC11 Alumina (Al2O3) Ceramic Thermocouple Protection Tubes and Multi-Bore Insulating Tubes offer superior thermal endurance and electrical protection. Manufactured from high-purity Aluminum Oxide (up to 99.7% Al2O3), these ceramic tubes provide outstanding high-temperature stability, capable of continuous operation in extreme heat environments up to 1600 to 1800 degrees Celsius without melting, softening, or structural deformation. Featuring high dielectric breakdown strength and excellent electrical volume resistivity, AC11 protection sheaths effectively isolate internal thermocouple wires from electromagnetic interference, signal crosstalk, and ambient gas contamination. Available in single-bore, double-bore, four-bore, and high-density multi-hole configurations, they ensure precise wire separation and rapid thermal transfer for accurate temperature monitoring. Chemically inert and non-porous, they resist harsh acid/alkali vapors, molten metal slag, and oxidizing atmospheres. MIDDIA provides full OEM/ODM manufacturing according to technical specifications, custom lengths, outer diameters, wall thicknesses, one-end closed or open configurations, low MOQ wholesale orders, and fast global delivery.
