Adapters Cone To Rubber Tubing

Adapters Cone to Rubber Tubing are fundamental laboratory connection components engineered to bridge the gap between rigid ground glass assemblies and flexible tubing networks. Manufactured from premium borosilicate glass, these adapters provide a highly reliable, leak-proof transition essential for safe fluid, gas, or vacuum transfer in diverse scientific operations.

Designed with a precision-ground male cone joint on one end and a specialized serrated nozzle on the other, these adapters ensure a tight, slip-resistant grip on rubber or silicone hoses. Their heavy-duty construction provides excellent resistance to thermal shock and chemical corrosion, making them perfect for vacuum filtration, gas introduction, and distillation systems.

Key Features

• Fabricated from high-purity borosilicate 3.3 glass for maximum chemical inertness and thermal resistance
  
• Precision interchangeable ground glass cones optimized for uniform sealing and vacuum retention
  
• Serrated, ribbed, or olive-style hose connections designed to prevent tubing slippage under pressure
  
• Robust wall thickness for reduced risk of breakage during assembly and intensive laboratory handling
  
• Available in a broad range of international standard joint sizes (e.g., 14/23, 19/26, 24/29, 29/32) with straight or right-angle configurations
• International Standards

Our laboratory connection adapters are manufactured to meet exact dimensional tolerances, perfectly aligning with standard global specifications for effortless integration and international export:

• ISO 383 – Laboratory Glassware – Interchangeable Conical Ground Joints
  
• DIN 12257 – Laboratory Glassware – Connectors with Conical Cones
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus
• Custom glass nozzle profiles, variable tubing attachment diameters, and specialized custom dimensions can be manufactured to match specific B2B client blueprints or proprietary apparatus lines.

Applications

Widely utilized across synthetic organic chemistry setups, academic teaching labs, vacuum extraction lines, inert gas purging systems, industrial pilot plants, and pharmaceutical testing environments requiring secure flexible-to-glass connections.
