Product Overview

Borosilicate Glass Balls are precision glass spheres engineered for chemically aggressive and thermally demanding environments where dimensional stability, corrosion resistance, and repeatable performance are essential. Engineered and tested across thousands of installations in flow control, dosing, and process equipment, these clear borosilicate glass balls deliver stable behavior in metering components and contact surfaces that see frequent chemical exposure and temperature variation.

Designed for industrial and sanitary applications, borosilicate glass spheres are highly resistant to corrosion and most acids and offer strong resistance to thermal shock. They support extended exposure to temperatures of up to 600’F290℃, making them a reliable choice for harsh environments that would degrade many alternative materials. Due to chemical inertia to most acids, borosilicate glass is particularly suitable for metering pumps and valves against strong oxidizing concentrations.

Manufactured and supplied by Shandong SDBALLS Industry Co., LTD, these borosilicate glass balls are supported by decades of manufacturing expertise, strict process control, and export-proven delivery capability. SDBALLS operates two factories with modern production equipment, exports products to more than 50 countries, and provides OEM and ODM support to meet global customer specifications with consistent quality.
