The product is a round sight glass fabricated from borosilicate glass and conforms to DIN 7080 standards. It is supplied by Hengshui Honghao Garment Factory in China and is intended for industrial level‑gauge assemblies. The glass disc offers high resistance to thermal shock and mechanical stress, making it suitable for pressure‑vessel and boiler environments. The supplier notes that a range of diameters is available to match different gauge housings.
In the glass industry, borosilicate compositions typically contain 80 % silica, 13 % boron oxide and small amounts of alkali oxides, which provides a low coefficient of thermal expansion. Typical thicknesses for round sight glasses run from 4 mm to 12 mm, a standard that balances strength and visibility. Standard temperature resistance for such glass is up to 500 °C, while pressure ratings commonly reach 10 bar for the usual thicknesses. Surface finish is polished to a smooth grade that facilitates cleaning and prevents fouling.
Primary users include chemical processing plants, petrochemical refineries, and food‑processing manufacturers that require reliable liquid‑level indication. The supplier can customise the disc size and offers optional certifications such as ISO or FDA upon request. Packaging is designed with protective pallets and cushioning to survive bulk handling, and trade terms may include FOB or CIF according to the buyer’s preference. Prospective importers should confirm exact dimensions, certification status and shipping incoterm with the supplier before placing an order.

Before placing an order, importers should verify the exact diameter, thickness and pressure rating required for their gauge assemblies, and request the latest DIN 7080 compliance report from Hengshui Honghao Garment Factory. It is prudent to confirm the supplier’s address and harbour trust tier, and to obtain a copy of any ISO or FDA certificates that will accompany the shipment. Asking for a sample or technical drawing can further reduce the risk of mismatched specifications.
Logistics planning should include a clear agreement on Incoterms, with FOB or CIF most commonly offered by the factory. Although the source data does not list a specific lead time, buyers are advised to ask the supplier to confirm production scheduling and estimated dispatch dates. Payment terms are typically negotiated per transaction, and it is advisable to request a pro‑forma invoice that outlines the agreed currency and any required advance payment. Confirming these details helps avoid unexpected delays at the port of loading.
Quality assurance should involve third‑party inspection before loading, focusing on visual clarity, dimensional accuracy and surface integrity of each glass disc. Importers can request a test report confirming thermal‑shock resistance and pressure‑hold performance according to DIN 7080 criteria. Documentation such as a certificate of conformity, material safety data sheet and the agreed certification (ISO or FDA) should be obtained and reviewed prior to customs clearance. These steps ensure the delivered product meets the technical requirements of the end‑user.
