Conflat (CF) UHV Reducer Tees

ConFlat (CF) UHV Reducer Tees: A Comprehensive Overview

ConFlat (CF) UHV Reducer Tees are essential components in the design and operation of ultra-high vacuum (UHV) systems. These specially designed tees allow for seamless transitions between different pipe or tube sizes while maintaining the integrity of the vacuum. Fabricated from 304L stainless steel and sealed with ConFlat (CF) knife-edge flanges, these reducer tees ensure reliable, leak-tight connections under the stringent conditions of ultra-high vacuum environments. TFM’s ConFlat (CF) UHV Reducer Tees are precision-engineered to meet the needs of industries such as semiconductor manufacturing, research, and space simulation, where maintaining the highest standards of vacuum performance is critical.

What are ConFlat (CF) UHV Reducer Tees?

ConFlat (CF) UHV Reducer Tees are vacuum fittings that enable multiple connections at varying flange sizes, providing a crucial role in UHV systems. The “tee” configuration typically has one larger port and one or two smaller ports, allowing for efficient routing and size adaptation of various vacuum components. The reducer aspect refers to the transition from a larger diameter to a smaller one, providing a seamless connection between different components such as pumps, gauges, and feedthroughs.

Constructed with 304L stainless steel, these tees are highly resistant to corrosion, ensuring that they maintain the vacuum integrity of the system even under extreme conditions. The ConFlat (CF) flange design ensures that these tees provide leak-tight, reliable seals, making them the ideal choice for critical vacuum applications.

Key Features of ConFlat (CF) UHV Reducer Tees

1. Premium 304L Stainless Steel Construction

Our ConFlat (CF) UHV Reducer Tees are made from 304L stainless steel, known for its high resistance to corrosion and excellent performance in vacuum applications. This material ensures a long lifespan and minimizes outgassing, which is essential for maintaining vacuum stability over time.

2. Knife-Edge ConFlat Flanges

The hallmark of the ConFlat (CF) design is the knife-edge flange, which creates a perfect, leak-tight seal when paired with a compatible gasket. This ensures that the UHV reducer tees maintain the integrity of the vacuum and prevent any unwanted gas leakage.

3. Versatile Reducer Configuration

These tees come in various configurations, providing a smooth transition between different flange sizes. This versatility makes them essential for adapting to different system setups and vacuum requirements, whether in laboratory research or industrial processes.

4. Vibration-Resistant, Through-Hole Bolt Holes

CF UHV Reducer Tees are designed with through-hole bolt flanges, ensuring that they remain securely fixed within the vacuum system. This feature helps to prevent any movement or loosening of connections, even in environments subject to vibrations or thermal expansion.

5. Modular and Customizable Design

TFM’s ConFlat (CF) UHV Reducer Tees are designed for easy integration into any UHV system. With customizable port sizes, threaded sides, and additional features like rotatable flanges, they offer flexibility for a wide variety of configurations.

Applications of ConFlat (CF) UHV Reducer Tees

ConFlat (CF) UHV Reducer Tees play a critical role in several industries where precise vacuum control is essential. Some common applications include:

  • Semiconductor Manufacturing: In semiconductor fabrication, where precise control over the vacuum is necessary for deposition, etching, and other processes, CF UHV Reducer Tees help integrate different components and maintain a stable environment.

  • Space Simulation: These tees are used in vacuum chambers that simulate space conditions for testing satellites, components, and scientific instruments before they are launched into space.

  • Material Science and Surface Research: In research labs, CF reducer tees are used to connect various vacuum components and ensure clean, controlled environments for material testing and surface science experiments.

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.
