The Precision Glass Sleeve Tube is a miniature precision glass component with an outer diameter of 2.77mm, an inner diameter of 1.91mm and a length of 45mm, designed to protect and guide optical paths and sensitive instrument components. The tube features uniform wall thickness and smooth inner and outer surfaces without burrs, ensuring consistent light transmittance and reliable fit during assembly. Manufactured from corrosion-resistant glass, the sleeve tube withstands acid and alkali environments while maintaining stable dimensional and optical properties. With strict tolerance control and crack-resistant construction, this precision sleeve delivers dependable long-term performance in miniature optical systems, analytical instruments and precision sensor assemblies.

• Uniform wall thickness: The evenly drawn wall provides consistent strength and optical behavior along the full 45mm length.
• Smooth inner and outer walls without burrs: The burr-free surfaces allow clean assembly and protect optical fibers and components from damage.
• Consistent light transmittance: The clear glass body transmits light uniformly, supporting stable performance in miniature optical paths.
• Acid and alkali corrosion resistant: The chemically stable material withstands aggressive cleaning agents and laboratory environments.
• Strict dimensional tolerance: OD, ID and length are controlled within narrow limits, guaranteeing accurate fit in precision assemblies.

The Precision Glass Sleeve Tube is designed for miniature optical and analytical systems that require precise, protective tubing. It is widely used as a protective sleeve for miniature optical paths, shielding fibers and light guides from contamination, bending and mechanical damage. In analytical instruments, the tube serves as a liner for micro instruments, providing a clean and chemically inert channel for sample flow and optical transmission. The component is also adopted in chromatography lab fittings, where its accurate dimensions and smooth bore support reliable connections between columns and detectors. Additionally, the sleeve tube works as a precision sensor sheath, protecting sensing elements while allowing light or signals to pass through with minimal interference.

• Strict dimensional tolerance control: Precise OD, ID and length ensure dependable fit and alignment during assembly.
• Perfect fitting during assembly: The smooth, burr-free surfaces mate cleanly with fittings, ferrules and instrument ports.
• Stable chemical property: Resistance to acids and alkalis keeps the tube clean and reliable in demanding laboratory conditions.
• Crack-resistant for long service life: The robust glass structure resists cracking under thermal and mechanical stress, delivering extended durability.
