Alumina Oval Two Bore Tubes

Alumina oval two bore tubes provide a compact, directionally stable ceramic form for applications requiring two isolated channels within a non cylindrical profile. The elongated oval shape supports keyed or constrained assemblies, while the dual bores maintain consistent separation for conductors, sensing elements, or media pathways. High purity alumina ensures reliable performance in elevated temperatures, corrosive environments, and electrically demanding systems.

Material Characteristics

These tubes are manufactured from high purity alumina engineered for thermal stability, mechanical strength, and electrical insulation. The material maintains dimensional accuracy under thermal cycling and resists oxidation and chemical exposure common in industrial and laboratory environments.

Design Advantages

• Oval geometry improves orientation control and reduces rotation within housings
• Dual bores provide isolated channels for paired elements
• Stable mechanical structure supports precise alignment
• Suitable for compact assemblies where round tubes cannot maintain position

Typical Applications

Alumina oval two bore tubes are used across instrumentation, thermal processing, and electrical systems where controlled separation and stable orientation are required. Common uses include thermocouple protection, multi lead insulation, vacuum feedthroughs, and high temperature sensor assemblies.

Performance Benefits

The combination of high purity alumina and an oval multi bore design delivers consistent performance in demanding environments. These tubes support long service life, predictable dielectric behavior, and reliable mechanical stability during installation and operation.

FAQ

What Are the Advantages of the Oval Profile?

The oval shape prevents rotation and maintains directional alignment, making it suitable for keyed channels or assemblies requiring fixed orientation.

How Are the Two Bores Used in Typical Applications?

The dual bores provide isolated pathways for paired wires, leads, or sensing elements, maintaining separation under thermal and mechanical stress.

Can These Tubes Withstand High Temperatures?

Yes. High purity alumina supports elevated temperature operation and maintains structural and dielectric stability during thermal cycling.

Are Custom Lengths or Tolerances Available?

Custom lengths and modified tolerances are often available depending on production capabilities and order requirements.
