Item Name:
Fused Quartz Tubing - 90mm x 2.5mm
SKU:
ABRQT133
Description:
Fused quartz tubing is produced by melting high-purity silica and forming it into a hollow tube with controlled inner and outer diameters for precision fit and consistent wall thickness. This tubing has an inner diameter of 85.00 mm and an outer diameter of 90.00 mm, with a standard length of 5 feet. In lampworking and scientific glassblowing, fused quartz is selected when the application demands extreme temperature capability, very low thermal expansion, and excellent resistance to thermal shock. Large-diameter quartz tubing like this is commonly used for high-heat process tubes, protective sleeves, and specialty builds where dimensional stability under sustained heat is critical and where standard glass materials are not suitable.
How it is used:
- Worked with a hydrogen and oxygen torch or other appropriate high-temperature heat source, since fused quartz requires higher working temperatures than borosilicate or soft glass
- Used to fabricate large high-temperature sleeves, housings, and process tube sections for scientific and industrial-style quartz work
- Cut and fire-polished for custom tube lengths, then joined to compatible quartz components for assemblies that must tolerate repeated heat cycling
- Used when the finished component must maintain shape and alignment under sustained heat, direct flame exposure, or rapid temperature changes
- Commonly chosen for builds where low thermal expansion is important for tight tolerances, seals, and stable alignment
