Conflat (CF) UHV Radius 45° Elbows

ConFlat (CF) UHV Radius 45° Elbows: Precision for Ultra-High Vacuum Systems

ConFlat (CF) UHV Radius 45° Elbows are key components in high-performance ultra-high vacuum (UHV) systems, offering an efficient solution for precise directional changes in vacuum lines. Made from durable 304L stainless steel and featuring ConFlat (CF) knife-edge flanges, these elbows ensure secure, leak-tight seals, maintaining optimal vacuum conditions for demanding applications.

At TFM, we specialize in producing CF UHV Radius 45° Elbows that meet the highest industry standards, designed for long-term use in vacuum systems where precision and reliability are paramount.

What Are ConFlat (CF) UHV Radius 45° Elbows?

ConFlat (CF) UHV Radius 45° Elbows are fittings designed to change the direction of vacuum lines at a 45° angle. The radius design helps minimize turbulence and ensures smooth, efficient flow within the vacuum system. These elbows are typically used when a more gradual directional change is needed compared to a 90° elbow, providing optimal vacuum performance without compromising system stability.

The 304L stainless steel construction ensures these elbows are both corrosion-resistant and durable, making them ideal for long-term use in harsh UHV environments. The ConFlat flanges create leak-tight seals, which are essential for maintaining the integrity of the vacuum system.

Key Features of ConFlat (CF) UHV Radius 45° Elbows

1. 304L Stainless Steel Construction

Our CF UHV Radius 45° Elbows are made from 304L stainless steel, which offers superior resistance to corrosion and high tensile strength. This material choice ensures that the elbows can withstand the stresses of long-term use in demanding UHV environments without compromising performance.

2. ConFlat Flanges for Leak-Tight Seals

Each elbow is equipped with ConFlat (CF) knife-edge flanges on both ends. These flanges ensure a leak-tight seal when paired with compatible gaskets, providing secure connections and maintaining the vacuum integrity necessary for UHV applications.

3. Smooth Radius Design

The 45° radius design ensures smooth, gradual directional changes that minimize vacuum flow disturbances and turbulence. This helps maintain a stable and consistent vacuum environment, which is essential for precision equipment and research.

4. Durable and Vibration-Resistant

These elbows are designed to withstand vibrations, temperature fluctuations, and mechanical stress, making them perfect for integration into dynamic UHV systems where environmental factors can impact system performance.

5. Versatile Integration

ConFlat (CF) UHV Radius 45° Elbows are compatible with a wide range of other CF-flanged components, allowing for flexible integration into various UHV system setups. Whether in semiconductor manufacturing, research labs, or vacuum chambers, these elbows provide a reliable and seamless solution.

Applications of ConFlat (CF) UHV Radius 45° Elbows

These elbows are commonly used in applications that require precise control of vacuum systems while maintaining a stable vacuum environment:

  • Semiconductor Manufacturing: Essential in cleanrooms and fabrication facilities, CF UHV Radius 45° Elbows are used to route vacuum lines in complex equipment setups without disrupting the vacuum conditions.

  • Space Simulation Chambers: Used in aerospace testing environments, these elbows direct vacuum lines to simulate space conditions, ensuring a controlled environment for component testing.

  • Vacuum Deposition Systems: In material science and thin-film deposition processes, these elbows facilitate smooth directional control of vacuum lines, ensuring consistent results in coating or surface treatment processes.

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.
