Quick-Release Tube Furnace Flange Set - KF Vacuum Port

The S4R Quick-Release Tube Furnace Flange Set — KF Vacuum Port provides a removable sealing system for laboratory furnace tubes requiring convenient access to vacuum or controlled-atmosphere connections.

The stainless-steel assemblies use a quick-release clamping design for easier opening and reassembly of the tube ends. A KF vacuum interface allows connection to compatible vacuum equipment, while additional gas, valve or gauge connections can be integrated according to the selected configuration.

The standard S4R set is supplied with the corresponding sealing components, quick-release clamps and fastening hardware. Standard configurations are available for commonly used quartz and ceramic furnace-tube diameters, with custom assemblies available on request.

Package Contents

• Tube furnace flange assemblies

• Quick-release clamp components

• Matching sealing components

• Required fastening hardware for the selected configuration

Technical Notes

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

• Ensure that all sealing surfaces and sealing components are clean and correctly positioned before assembly.

• Tighten tube-end fastening components evenly to reduce localized mechanical loading on the furnace tube.

• The KF connection size and auxiliary port arrangement depend on the selected configuration and should be confirmed when ordering.

• Vacuum performance depends on the complete system, including the tube, seals, flange installation, KF connections and vacuum equipment.
