At TFM, we pride ourselves on manufacturing CF UHV Miter 90° Elbows that meet the stringent standards required for precision vacuum systems. Our products ensure that your UHV setup maintains the highest levels of vacuum integrity and performance.

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

ConFlat (CF) UHV Miter 90° Elbows are vacuum fittings designed to change the direction of vacuum lines at a 90° angle. These elbows are essential for routing vacuum lines in complex configurations while maintaining consistent vacuum performance. The CF flanges on both ends of the elbow provide an airtight seal, ensuring that the integrity of the vacuum is preserved.

These elbows are made from 304L stainless steel, which is known for its excellent corrosion resistance, strength, and suitability for high-vacuum applications. The knife-edge ConFlat flanges provide reliable sealing, which is essential for UHV applications where even the smallest leak can significantly impact system performance.

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

1. Durable 304L Stainless Steel Construction

Our ConFlat (CF) UHV Miter 90° Elbows are constructed from 304L stainless steel, offering superior corrosion resistance and long-term durability. This material ensures that the elbows perform optimally in UHV environments, where high vacuum integrity is crucial.

2. Leak-Tight ConFlat Flanges

Each CF UHV Miter 90° Elbow is equipped with knife-edge ConFlat flanges, which create a secure, leak-tight seal when mated with compatible gaskets. This feature is vital in maintaining the ultra-high vacuum necessary for critical applications.

3. Precise 90° Bend for Directional Control

The 90° miter bend allows for precise directional control of vacuum lines, enabling smooth integration into complex vacuum system layouts. The elbow ensures that the flow of gases or materials within the system is unobstructed and consistent.

4. Vibration and Stress Resistance

Designed to withstand mechanical stress and vibrations, CF UHV Miter 90° Elbows provide secure connections that help maintain system stability, even under fluctuating pressure conditions or thermal cycles.

5. Versatile Integration

These elbows are compatible with a wide range of CF flanged components, making them ideal for use in various UHV applications, such as semiconductor manufacturing, space simulation, and material science research.

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.
