Swagelok to Male NPT Elbow

Swagelok to Male NPT Elbow: 90° Tube-to-Thread Fitting for Secure, Leak-Free Connections

The Swagelok to Male NPT Elbow from TFM offers a robust, precision-machined solution for creating 90-degree connections between Swagelok compression fittings and male NPT (National Pipe Thread) ports. Designed to deliver leak-proof, torque-free seals, these elbow fittings are essential in instrumentation, vacuum, and fluid systems where compact routing and reliable performance are critical.

Each elbow fitting combines Swagelok’s trusted tube-gripping technology with tapered NPT threads, allowing operators to securely connect tubing to threaded ports while navigating tight installation spaces.

Key Features of Swagelok to Male NPT Elbow Fittings:

  • Leak-Proof, Torque-Free Seals
    The Swagelok end of the elbow delivers a gas-tight connection without over-torquing, protecting tubing integrity and ensuring long-term performance.

  • 90-Degree Elbow Geometry
    Enables clean, efficient right-angle transitions between tubing and threaded ports, minimizing strain and space consumption in dense systems.

  • Prevention of Costly Leaks
    Designed for critical instrumentation setups, these elbows help eliminate hazardous leaks in gas or liquid lines, reducing maintenance and downtime risks.

  • Material Options for System Compatibility

    • Stainless Steel Swagelok to Male NPT Elbow: Ideal for gas applications, including vacuum, process control, and chemical delivery systems.

    • Brass Elbow Option: Suitable for water systems or lower-pressure applications, offering corrosion resistance and cost-effectiveness.

  • Precision Threading & Tube Grip
    The NPT male threads conform to industry standards for tapered sealing, while the Swagelok end features dual-ferrule compression technology for reliable, repeatable assembly.

Applications:

  • Connecting gas tubing to threaded manifolds or regulators

  • Integrating instrumentation panels or control enclosures

  • Adapting tubing runs in vacuum systems, gloveboxes, or gas panels

  • Supporting HVAC, hydraulic, and water flow distribution setups

  • Retrofitting tight or confined spaces where 90° bends are required

TFM provides a broad selection of Swagelok-compatible elbows, tees, straight fittings, and adapters in various sizes and materials. The Swagelok to Male NPT Elbow is a core component for any engineer seeking reliable, compact connections between tubing and threaded ports in critical applications.

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.
