Fluorocarbon Gaskets (molded) for ConFlat (CF) UHV Flanges

Fluorocarbon Gaskets (Molded) for ConFlat (CF) UHV Flanges

TFM’s Fluorocarbon Gaskets (Molded) for ConFlat (CF) UHV Flanges are specially engineered to deliver superior sealing performance in ultra-high vacuum (UHV) applications. Crafted from high-quality fluorocarbon materials like Viton® or equivalent, these molded gaskets are perfect for maintaining leak-tight seals under extreme conditions. Whether in semiconductor manufacturing, vacuum processing, or research environments, TFM’s molded fluorocarbon gaskets provide exceptional resistance to harsh chemicals, extreme temperatures, and high vacuum levels, ensuring reliable and durable sealing.

Key Features

  • Molded Design for Precision
    The molded design ensures that each gasket fits perfectly with ConFlat (CF) UHV flanges, providing uniform compression across the sealing surface. This guarantees a reliable seal and minimizes the risk of leaks, even in demanding environments.

  • High-Quality Fluorocarbon Material
    Made from top-tier fluorocarbon compounds, these gaskets exhibit excellent chemical resistance and high-temperature stability. The material ensures durability and optimal performance even in harsh operating environments.

  • Temperature and Chemical Resistance
    Fluorocarbon gaskets are designed to withstand extreme temperature ranges, from cryogenic conditions up to high temperatures (typically -20°C to 250°C, or -4°F to 482°F). These gaskets also provide outstanding resistance to chemicals, including acids, bases, and solvents, making them ideal for a wide range of applications.

  • Leak-Tight Performance
    These gaskets are specifically engineered to create a leak-tight seal under ultra-high vacuum conditions. Their superior sealing capability prevents gas or fluid leakage, ensuring the integrity of the system in critical applications.

  • Long-Term Durability
    The molded fluorocarbon gaskets are resistant to compression set, ensuring they maintain their shape and sealing properties over time. This long-term durability reduces the need for frequent gasket replacements, offering a cost-effective solution for high-performance systems.

Applications

  • Ultra-High Vacuum Systems
    Perfect for use in UHV systems, TFM’s molded fluorocarbon gaskets provide a reliable seal for equipment where minimal outgassing and low leak rates are essential. They are commonly used in research labs, semiconductor manufacturing, and other precision vacuum applications.

  • Semiconductor Manufacturing
    In semiconductor production, these gaskets are used in critical vacuum-based processes such as plasma etching, chemical vapor deposition (CVD), and physical vapor deposition (PVD), ensuring a clean and stable vacuum environment.

  • Research and Laboratory Applications
    These gaskets are ideal for applications in particle accelerators, electron microscopes, and other vacuum-based research equipment, where consistent and reliable vacuum conditions are required.

  • Aerospace and Vacuum Technologies
    Fluorocarbon gaskets are also suitable for aerospace applications, including satellite systems and vacuum chambers, where performance and durability in extreme vacuum conditions are crucial.

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.
