Swagelok VCR Female Unions: Precision Metal Gasket Connections for UHV and High-Purity Gas Systems

Swagelok VCR Female Unions from TFM are engineered to provide secure, metal-to-metal face-seal connections for low-pressure gas and ultra-high vacuum (UHV) environments. Designed with female VCR ports on both ends, these unions ensure leak-free, contamination-resistant performance in critical applications such as helium leak testing, semiconductor processing, and analytical gas delivery.

Constructed from corrosion-resistant 316L stainless steel, Swagelok VCR Female Unions are compatible with stainless steel or copper gaskets, offering unmatched sealing stability at elevated temperatures and under extreme vacuum conditions.

Key Features of Swagelok VCR Female Unions:

  • Leak-Tight Face-Seal Technology
    The VCR design creates a metal gasket seal free of elastomers, ideal for ultra-clean and high-temperature applications.

  • High-Temperature Resistance

    • With stainless steel gaskets, these fittings withstand bakeout temperatures up to 538°C, enabling system sterilization and outgassing.

    • With copper gaskets, they remain reliable up to 204°C, suitable for most general laboratory and industrial gas setups.

  • UHV Compatibility
    Designed to operate at pressures as low as 10⁻⁹ Torr, these unions are suitable for use in research labs, mass spectrometry, and leak-checking systems.

  • Female-to-Female Face-Seal Configuration
    Perfect for joining two male VCR connectors in a compact, leak-proof union without introducing dead volume or turbulence.

  • Material Purity and Durability
    Made from 316L stainless steel with a precision-machined sealing surface, ensuring corrosion resistance, gas purity, and long operational life.

Applications:

  • Gas transfer between lecture bottle regulators and instrumentation

  • Joining two male VCR fittings in vacuum or process panels

  • High-purity gas connections in semiconductor and cleanroom systems

  • Leak-tight UHV line integration in R&D and analytical labs

  • Replacing worn or contaminated unions in legacy gas systems

TFM also offers a full range of Swagelok VCR accessories, including male/female adapters, elbow and tee unions, caps, nuts, and gaskets—allowing for seamless integration and maintenance across complex gas delivery infrastructures.

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.
