Swagelok Union Tees

Swagelok Union Tees: Leak-Free Tube Branching for Instrumentation and Process Systems

Swagelok Union Tees from TFM are engineered to provide a three-way tube connection—ideal for branching or combining flow paths within gas or liquid systems. With Swagelok’s proven dual-ferrule compression technology, these tees deliver leak-proof, torque-free seals at all tubing intersections, ensuring reliable performance in high-purity and critical process environments.

Designed for use in instrumentation panels, vacuum lines, fluid manifolds, and gas delivery systems, Swagelok Union Tees offer precision alignment, repeatable assembly, and system compatibility with both fractional and metric tubing.

Key Features of Swagelok Union Tees:

  • Leak-Proof, Torque-Free Sealing
    Swagelok’s design ensures secure tube connections without overtightening, minimizing installation error and preserving tubing integrity across all three ports.

  • Three-Way Flow Path Configuration
    The T-shaped geometry supports straight-through flow with a perpendicular branch—ideal for diverting or monitoring process fluids or gases.

  • Prevention of Costly and Hazardous Leaks
    Built for mission-critical systems, these tees reduce the risk of leaks that could compromise safety, process accuracy, or product purity.

  • Material Flexibility for Application-Specific Use

    • Stainless Steel Union Tees: Recommended for gas systems, high-temperature, or chemically reactive environments.

    • Brass Union Tees: Suitable for water systems, low-pressure applications, and non-corrosive fluids.

  • High-Precision Machining
    Manufactured to tight tolerances for seamless tube alignment and consistent seal reliability in repeated installations.

Applications:

  • Branching process lines in gas distribution manifolds

  • Diverting coolant flow in precision equipment

  • Pressure and vacuum tap-offs for instrumentation monitoring

  • Analytical or sampling access points in fluid systems

  • General-purpose tubing layouts in lab, plant, or OEM designs

TFM also supplies a full range of Swagelok-compatible fittings, including union crosses, bulkhead adapters, NPT transitions, and elbows, allowing complete customization and extension of your tubing system with Swagelok reliability.

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.
