The product is a borosilicate glass tube designed for visual liquid level indication. It features a red line between two white lines painted on the tube wall, allowing easy reading of the level. The tube is made from standard borosilicate glass with a thermal expansion coefficient of about 3.3×10⁶/°C. Available outside diameters range from ½ inch to 1 inch, and pressure ratings vary from 90 psi to 600 psi depending on finish, diameter and length.
Standard borosilicate glass typically contains about 80% SiO2 and 13% B2O3, giving it resistance to thermal shock. Tolerances for the outside diameter are usually ± 0.005 inch for the sizes offered. End finishes can be cut, ground or fire‑polished, each providing a different surface roughness that influences pressure capability. In laboratory and process equipment, such tubes are commonly supplied in lengths between 100 mm and 500 mm, which is a typical range for this class of glass.
The tubes are used in tanks, reservoirs and low‑pressure boilers where a clear visual indicator is required. Equipment manufacturers and industrial plant builders are the primary buyers. The supplier lists the product under the harbour trust tier but provides no public MOQ, lead‑time or incoterm details, so interested importers should request these terms directly. Confirm packaging options, such as bulk cartons or individual protective sleeves, before placing an order.

Before placing an order, verify the supplier’s business licence and request a recent material test report confirming borosilicate composition and pressure rating. Ask for references to previous export shipments and confirm that the factory address in Hengshui matches the documentation provided.
Logistics should be clarified by confirming the preferred Incoterm, likely FOB Tianjin or Shanghai, and the expected shipping lead time from Hebei Province. Discuss payment terms, such as a letter of credit, and any required pre‑shipment inspections. Ensure that packaging details, including bulk cartons with foam separators, meet your handling requirements.
Implement quality assurance by arranging a third‑party inspection of the tube dimensions, end finish and pressure test results. Request a certificate of conformity and a mill test report before loading. Maintaining records of these documents will support smooth customs clearance and downstream quality control.
