Hose Connectors

GISCOM  Hose Connectors are precision-manufactured borosilicate glass adapters designed to create secure, leak-free connections between flexible hoses and rigid laboratory tubing. They offer a reliable interface for fluid transfer, vacuum applications, and gas handling systems. Their durability, chemical resistance, and dimensional accuracy make them essential components in laboratory glassware assemblies used in research, industrial, and analytical environments.

Key Features

• Made from high-quality Borosilicate Glass 3.3, ensuring excellent chemical and thermal resistance
• Rugged design for secure connections between hoses, tubes, and glass apparatus
• Precision-formed ridges provide a strong grip and minimize the risk of hose slippage
• Smooth internal flow path reduces turbulence and ensures consistent fluid transfer
• Fully compatible with standard laboratory hoses and tubing sizes
• High durability for repeated use, cleaning, and autoclaving
• Ideal for glassblowing companies and laboratories assembling custom glass systems
