Product detail

ceramic thermocouple insulators ceramic insulator tube

When it comes to requiring protection, resistance, and durability, alumina, also known as aluminum oxide, is the top choice. Alumina's strength and resilience make it the preferred material for demanding conditions where resistance to deterioration and deformation is crucial. Alumina ceramic tubes possess a range of characteristics and features that make them highly suitable for various applications. This high-quality tubing exhibits exceptional hardness, excellent chemical resistance, long wear life, and outstanding insulation properties. Its diverse properties have made it a staple in industries that necessitate tubing capable of withstanding extreme temperatures.


The quality of an alumina tube relies on its purity, with higher purity levels resulting in greater resistance. Mascera Ceramics produces tubes with a purity factor of 95% or higher. The tubes can be shaped into various diameters to suit specific applications. Our alumina tubes exhibit high thermal conductivity and can endure significant compression.


Thanks to its dielectric properties, an alumina tube is ideal for insulating electrical connections. The ceramic material's density provides protection against gas or liquid intrusion. With exceptional resistance to wear and abrasion, as well as its stability up to 1800℃, it ensures longevity and reliability. Once installed, it can withstand hazardous or hostile conditions without compromising performance.
