Gauge Glass Tubes
Product Description
Colored Borosilicate Glass Tubes & Rods are manufactured by incorporating selected coloring compounds into the glass formulation, producing stable color throughout the glass rather than applying color only to the external surface. They are available in transparent, translucent and opaque finishes for different visual and functional requirements.
The hollow glass tubes are suitable for applications requiring an internal passage, such as indicator tubes, lighting components, decorative vessels, instrument parts and fabricated glass assemblies. Solid glass rods are commonly used for component fabrication, lampworking, glass decoration, stirring rods, handles and other processed glass products.









Key Features and Advantages
Stable, integral coloration
The color is incorporated into the glass body, providing better durability than a simple painted surface.
Multiple color options
Transparent, translucent and opaque shades are available for identification, decoration, light control and product differentiation.
Good thermal resistance
Borosilicate grades have low thermal expansion and better resistance to controlled temperature changes than conventional soda-lime glass.
Good chemical durability
Suitable for contact with water, many acids, salt solutions and organic substances under appropriate operating conditions.
Easy secondary processing
Tubes and rods can be cut, flame-polished, bent, sealed, drilled or further fabricated according to the required application.
Sizes
Colored glass tubes and rods are available in standard and custom sizes.
Glass Tube OD: 3–200 mm
Glass Rod Diameter: 2–50 mm
Standard Length: 300–1,500 mm
Customization: Diameter, wall thickness and cut length can be produced according to your requirements.
Other sizes are available upon request.
