Quartz Threaded Tube

Quartz threaded tubes are made from high-purity fused silica and feature precision-cut threads for secure sealing, connection, or assembly. These tubes combine excellent thermal shock resistance, high-temperature endurance, and chemical stability.
We offer complete customization of thread size, pitch, OD, ID, length, and end-face processing. Threaded quartz tubes are commonly used in laboratory systems, furnace equipment, reaction chambers, vapor transport, and custom high-purity sealing applications.

we can customized all kinds of quartz glass product service

Frequently asked questions

It is used for sealing, connecting, or securing components in laboratory systems, furnace setups, high-purity reaction chambers, gas flow systems, and custom industrial equipment.

We can customize OD, ID, wall thickness, and length according to project requirements. Tolerances can be adjusted for precision sealing applications.

Yes. We can produce compatible quartz stoppers, threaded caps, or mating parts to match the tube’s thread dimensions.

Yes. Thread type, pitch, length, and depth can be fully customized based on drawings or specifications. Both internal and external threads are available.

Fused silica threads maintain integrity at temperatures up to 1050°C continuous and 1200°C short-term, depending on the design and application.

Please provide OD, ID, length, thread specifications (pitch, length, type), quantity, and processing requirements. A drawing is highly recommended for accuracy.
