The S4R Tube Furnace Flange Set provides a removable tube-end connection system for laboratory furnaces operated with controlled gas flow. Two matching 304 stainless steel flange assemblies are installed at opposite ends of the furnace tube, providing dedicated inlet and outlet interfaces for the external gas line. Sealing rings and fastening hardware are supplied with the assembly.
Key Features
✓ 304 stainless steel flange construction
✓ Matched two-end flange set
✓ Dedicated gas inlet and outlet connection ports
✓ Removable mechanical clamping design
✓ Sealing rings and fastening hardware included
✓ Standard and custom tube sizes available
Typical Applications
• Laboratory tube furnace assemblies
• Controlled-atmosphere thermal processing
• Inert-gas purging
• Continuous process-gas flow
• Quartz and alumina furnace-tube systems
• Materials research and thermal-treatment setups

Package Contents
• Two 304 stainless steel tube-end flange assemblies
• Matching sealing rings
• Required fastening screws and assembly hardware
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 fastening hardware progressively and evenly to limit localized mechanical loading on the furnace tube.
• The external connection is threaded; the exact thread standard and nominal size depend on the selected configuration and should be confirmed when ordering.
• No specific maximum pressure, vacuum level or operating-temperature rating is stated for this assembly unless defined for a particular configuration.
