ConFlat (CF) UHV Full Nipples are essential components in ultra-high vacuum (UHV) systems, designed to provide secure, leak-tight connections between various vacuum components. Crafted from 304L stainless steel, these nipples are highly resistant to corrosion and feature ConFlat (CF) knife-edge flanges, ensuring a reliable seal that meets the stringent requirements of high-vacuum environments.

At TFM, we specialize in manufacturing CF UHV Full Nipples that deliver exceptional performance and durability, even in the most demanding UHV applications.

What Are ConFlat (CF) UHV Full Nipples?

ConFlat (CF) UHV Full Nipples are straight, cylindrical connectors designed to join two vacuum components in a UHV system. The full nipple design provides an extended length, allowing for more flexibility in system configurations and easier alignment of components. These nipples are equipped with CF flanges on both ends, creating secure, leak-tight connections that are essential for maintaining the integrity of the vacuum system.

The 304L stainless steel construction ensures that these nipples are highly durable, resistant to corrosion, and suitable for long-term use in UHV systems. Additionally, the ConFlat flanges create a reliable seal, which is crucial in maintaining the high vacuum levels necessary for various industrial and research applications.

Key Features of ConFlat (CF) UHV Full Nipples

1. 304L Stainless Steel Construction

Each CF UHV Full Nipple is made from high-quality 304L stainless steel, which offers superior strength, corrosion resistance, and minimal outgassing. This makes it ideal for use in UHV systems where cleanliness and stability are critical.

2. ConFlat Flanges for Leak-Tight Seals

The CF flanges on both ends of the nipple provide a knife-edge seal when paired with compatible gaskets, ensuring that your vacuum system maintains a strong, leak-free seal under demanding conditions. This is crucial for applications that require stable and consistent vacuum levels.

3. Extended Length for Flexible Integration

The full nipple design offers an extended length, which allows for more flexible and adaptable integration into complex UHV system configurations. It makes connecting two components easier, particularly when there is a need for more space between them.

4. Durable and Vibration-Resistant

The 304L stainless steel material ensures that the nipples are not only durable but also resistant to vibration and mechanical stress. This durability is essential for maintaining the integrity of the system in dynamic environments where mechanical vibrations may occur.

5. Versatile Compatibility

ConFlat (CF) UHV Full Nipples are compatible with a wide range of ConFlat-flanged components, such as valves, flanges, and chambers, providing seamless integration into various UHV setups. Their flexibility makes them ideal for applications across industries such as semiconductor manufacturing, research, and aerospace.

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.
