The S4R Stainless Steel Tube Furnace Flange provides a removable sealing interface for compatible laboratory furnace tubes used with gas-flow or vacuum systems. The assembly combines a 304 stainless steel flange body, silicone sealing rings and mechanical clamping components to seal around the tube while providing an interface for external gas or vacuum connections. Standard sizes are available for commonly used quartz furnace tubes, with custom configurations available for specific laboratory assemblies.

Technical Notes

• Select the flange according to the actual outside diameter of the furnace tube.

• Sealing rings and tube contact surfaces should be clean and correctly positioned before assembly.

• Tighten the flange assembly progressively and evenly to reduce localized mechanical loading on the furnace tube.

• Vacuum performance depends on the complete installation, including the furnace tube, seals, flange assembly, external connections and vacuum equipment.

• No specific vacuum level, maximum pressure or sealing temperature is specified unless stated for a defined configuration.

• Compatibility with alumina, mullite or other ceramic furnace tubes should be confirmed before ordering.

Supply

Standard & Custom Configurations Available
Supply configuration depends on the selected tube diameter and connection arrangement

Selection & Custom Configuration

Standard configurations are available for quartz furnace tubes with outside diameters of 25, 30, 40, 50, 60, 80 and 100 mm. For non-standard tube diameters or specific connection arrangements, please provide the tube outside diameter, required connection configuration and quantity. Compatibility with other furnace-tube materials should be confirmed before ordering.
