Enhance Your Vacuum System with Multiport Cluster Conflat® (CF) Flanges from TFM

In the world of ultra-high vacuum (UHV) systems, versatility and reliability are paramount. Multiport Cluster Conflat® (CF) flanges offer a convenient and efficient solution for complex systems that require multiple connections without sacrificing the integrity of the vacuum seal. At TFM, we offer a range of high-quality multiport cluster flanges, designed to meet the demands of advanced research and industrial applications.

What Are Multiport Cluster Conflat® Flanges?

A Multiport Cluster Conflat® flange is a specialized flange featuring multiple ports, designed to allow multiple vacuum connections from a single point of interface. These flanges are ideal for systems requiring multiple connections for instruments, vacuum pumps, viewports, or other components without taking up additional space. With Conflat® (CF) technology, these multiport flanges provide metal-to-metal seals using the knife-edge design and copper gaskets, ensuring leak-tight performance in UHV applications.

Key Features of Multiport Cluster CF Flanges

  • Multiple Ports in One Flange: A cost-effective and space-saving solution for systems with several connections.

  • ConFlat® Design: The knife-edge sealing design with copper gaskets ensures a leak-tight, vacuum-tight seal down to pressures as low as 10⁻¹² Torr.

  • Precision Engineering: CNC-machined for accuracy and flatness, ensuring perfect alignment and consistent performance.

  • Durable Material: Typically manufactured from 304L stainless steel, known for its corrosion resistance and durability under extreme vacuum conditions.

  • Standard Compatibility: Fully compatible with other CF-flange components, making integration into existing systems straightforward.

Advantages of Multiport Cluster CF Flanges

  • Space Efficiency: Reduce the need for multiple individual flanges, optimizing available space in tight setups.

  • Customization Options: Available in a range of port sizes and configurations to suit specific application needs.

  • Simplified Vacuum System Design: Minimize the number of flanges and seals required, reducing the complexity of your vacuum setup.

  • Durable and Reliable: Provides a reliable, high-quality vacuum seal for systems operating under demanding conditions.

Applications for Multiport Cluster CF Flanges

Multiport Cluster CF flanges are ideal for use in a variety of UHV applications, including:

  • Thin film deposition systems

  • Surface science research chambers

  • Particle accelerators and synchrotron beamlines

  • Semiconductor manufacturing equipment

  • Mass spectrometry and other analytical instruments

These flanges are perfect for complex systems where multiple connections are needed but space and cost are concerns.

FAQ

Tube fittings are designed for tubes (measured by outside diameter and wall thickness) used in high-pressure and instrumentation applications, whereas pipe fittings are for pipes (identified by nominal pipe size) primarily used in fluid transport.

 

Common valve types include ball valves, gate valves, check valves, butterfly valves, and globe valves. Each serves a specific function—from quick shutoff (ball/gate valves) to flow regulation (globe valves).

 

  • For tubing, measure the outside diameter; for pipes, refer to the nominal pipe size (using conversion charts if needed). Always match the valve or fitting size to your pipe’s dimensions and flow requirements.

  • Frequently used thread types include NPT (National Pipe Tapered), BSP (British Standard Pipe), and UNC, along with slip-fit options that rely on compression or fusion rather than threads.

Interchangeability depends on manufacturer specifications and certification. Always verify compatibility via manufacturer guides or certified interchangeability charts.

 

  • A coupling is a short, straight fitting used to join two pipes or tubes. It provides a secure, leak-tight connection and can sometimes serve to extend or repair piping runs.

Consider valve type, pressure and temperature ratings, material compatibility with your fluid, actuation method (manual or automatic), and maintenance requirements.

 

  • Valves regulate flow by opening, closing, or partially obstructing the pathway. Their mechanisms (such as the rotation of a ball or the linear movement of a gate) determine the speed and precision of flow control.

  • A flange is a flat, circular component used to connect pipes, valves, or other equipment. Bolted together with gaskets, flanges provide a secure, leak-proof joint that facilitates both assembly and maintenance.

  • Manual valves require physical operation via handles or levers, whereas actuated valves use mechanisms—pneumatic, electric, or hydraulic—to open and close automatically or remotely.

  • Issues include leaks caused by improper installation, over-tightening, degraded seals, material incompatibility, and fatigue from repeated cycling. Regular inspection and proper installation practices help mitigate these problems.

Regular maintenance involves periodic inspections, cleaning or replacing worn seals, ensuring proper torque during installation, and adhering to manufacturer guidelines and local plumbing codes to preserve system integrity.
