These elbows are engineered with 304L stainless steel and ConFlat (CF) knife-edge flanges, ensuring reliable, leak-tight seals for optimal performance in demanding vacuum environments.

At TFM, we specialize in manufacturing CF UHV Radius 90° Elbows that meet the strictest industry standards. These elbows are ideal for a variety of applications that require precise and stable vacuum control.

What Are ConFlat (CF) UHV Radius 90° Elbows?

ConFlat (CF) UHV Radius 90° Elbows are fittings designed to change the direction of vacuum lines at a 90° angle, with a smooth radius that reduces turbulence and ensures a consistent vacuum flow. These elbows are ideal for routing vacuum lines in complex configurations while preserving the vacuum’s integrity.

Crafted from 304L stainless steel, these elbows are durable and resistant to corrosion, making them suitable for long-term use in challenging environments. The ConFlat flanges on both ends of the elbow create secure, airtight seals when used with compatible gaskets, ensuring that the vacuum system maintains its high performance.

Key Features of ConFlat (CF) UHV Radius 90° Elbows

1. High-Quality 304L Stainless Steel Construction

Our CF UHV Radius 90° Elbows are made from 304L stainless steel, providing excellent corrosion resistance and strength. This material choice ensures that the elbows perform optimally in UHV environments, where vacuum integrity is paramount.

2. Leak-Tight ConFlat Flanges

Each CF UHV Radius 90° Elbow comes equipped with knife-edge ConFlat flanges, offering a secure, leak-tight seal. This feature is critical in maintaining ultra-high vacuum conditions, as even the smallest leaks can significantly affect system performance.

3. Smooth Radius for Optimal Vacuum Flow

The radius design of the elbow minimizes flow restrictions and turbulence, ensuring that the vacuum system maintains consistent pressure and gas flow. This design also helps reduce stress on the vacuum pump and enhances overall system stability.

4. Durability and Resistance to Vibration

These elbows are built to withstand mechanical stress, vibration, and thermal fluctuations, making them ideal for demanding environments where vacuum integrity must be maintained despite changes in pressure or temperature.

5. Versatile Integration

ConFlat (CF) UHV Radius 90° Elbows are compatible with a wide range of CF-flanged components, making them suitable for use in many types of UHV systems. Whether you are setting up semiconductor manufacturing equipment, space simulation chambers, or vacuum deposition systems, these elbows provide seamless integration.

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.
