The item is a borosilicate glass tube offered in a variety of shapes such as cone and H‑type profiles. It is supplied in clear, amber, blue, black, green, pink, purple and yellow colours, each produced from standard borosilicate glass. The supplier can also fabricate tubes to customer‑specific designs, including custom diameters and lengths. The base material provides high resistance to thermal shock and chemical attack.
Standard borosilicate glass typically contains 80% silica and 13% boric oxide, giving a thermal expansion of about 3.3×10⁶/°C. Diameter options commonly range from 2 mm to 25 mm, with lengths up to 500 mm being typical for industrial use. Pressure tolerance for such tubes is usually up to 300 psi, depending on wall thickness and finish. The colour additives are incorporated during melting and meet standard optical clarity requirements for flow‑meter and appliance applications.
These tubes are employed in flowmeters, household electrical appliances and other devices where a transparent conduit is needed. Manufacturers of fluid handling equipment and consumer appliance makers are the main customers. The listing does not disclose MOQ, lead‑time or incoterm specifics, so buyers should request this information directly from the supplier. Packaging is offered in bulk bundles or individually wrapped units, depending on the order size.

Before committing to a purchase, obtain the supplier’s business registration and, if possible, an export licence verification. Request a recent material test report that confirms the borosilicate composition, colour consistency and pressure rating for the specific tube configuration you need.
Clarify logistics by asking which Incoterm the supplier prefers, such as FOB Shanghai or CIF a destination port, and verify the estimated lead time from order confirmation to shipment. Discuss payment terms, commonly a documentary letter of credit, and ensure that packaging details meet your handling and storage requirements.
Arrange a third‑party inspection to check dimensions, colour uniformity and surface finish before loading. Insist on a mill test report and a pressure test certificate to substantiate the claimed performance. Keeping these documents will aid customs clearance and downstream quality assurance.
