ConFlat (CF) UHV Standard Tees: Precision Components for Ultra-High Vacuum Systems

ConFlat (CF) UHV Standard Tees are critical components in the design and optimization of ultra-high vacuum (UHV) systems. These tees offer a reliable means of connecting multiple vacuum tubes or components of different sizes, all while maintaining an airtight, leak-free seal. Typically made from 304L stainless steel and featuring ConFlat (CF) knife-edge flanges, these tees are designed to meet the stringent requirements of UHV environments, which demand precision and durability. At TFM, we manufacture high-quality CF UHV Standard Tees that are perfect for industries requiring ultra-clean and controlled environments, such as semiconductor fabrication, research laboratories, and aerospace testing.

What Are ConFlat (CF) UHV Standard Tees?

ConFlat (CF) UHV Standard Tees are specialized vacuum fittings that allow for the integration of multiple components into a single system. The “tee” configuration typically consists of a main body with one or more side branches, which can be used to connect different parts of the system or adapt between different flange sizes. The reliable CF flange ensures a perfect seal, maintaining the integrity of the vacuum system even in harsh conditions.

The standard tees are designed for use in systems that require precise control over vacuum pressure, and they are compatible with a wide range of UHV equipment, including gauges, pumps, and feedthroughs.

Key Features of ConFlat (CF) UHV Standard Tees

1. High-Quality 304L Stainless Steel Construction

Our ConFlat (CF) UHV Standard Tees are made from 304L stainless steel, a material known for its excellent corrosion resistance and strength. The stainless steel construction ensures long-term durability, resistance to outgassing, and superior performance in UHV environments.

2. Knife-Edge ConFlat Flanges

Each tee is equipped with knife-edge ConFlat flanges that create a perfect, leak-tight seal when paired with a compatible gasket. This is a key feature for maintaining the ultra-high vacuum integrity required in critical applications.

3. Standard UHV Configurations

These tees come in a variety of standard sizes and configurations, allowing for smooth integration into UHV systems. Whether connecting different flange sizes or adapting to multiple components, the standard design ensures flexibility and compatibility with numerous vacuum system parts.

4. Vibration-Resistant Design

ConFlat (CF) UHV Standard Tees are engineered with a robust design that ensures secure, vibration-resistant connections. This is particularly important for maintaining system stability in environments with fluctuating mechanical conditions or thermal expansion.

5. Multiple Ports for Versatility

The standard tee configuration features multiple ports, allowing for the simultaneous connection of various vacuum components. Whether you need to integrate gauges, pumps, or other equipment, these tees offer flexibility for your UHV setup.

Applications of ConFlat (CF) UHV Standard Tees

ConFlat (CF) UHV Standard Tees are commonly used in a variety of industries where ultra-clean and controlled vacuum conditions are necessary. Some of the primary applications include:

  • Semiconductor Manufacturing: These tees are used in semiconductor fabrication, where controlling the vacuum environment is crucial for deposition, etching, and other processes. They provide flexible connections to various equipment, such as pumps, gauges, and chambers.

  • Aerospace and Space Simulation: In space simulation chambers, CF UHV Standard Tees are used to create precise, leak-tight connections for testing components under vacuum conditions that mimic space. This is critical for ensuring the performance of aerospace materials and systems.

  • Material Science Research: Laboratories conducting surface science and material research rely on CF UHV Standard Tees to ensure clean, stable vacuum conditions during experiments. These tees help integrate components like electron microscopes, thin film deposition systems, and other scientific instruments.

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.
