1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the Swagelok Alloy C-276 Plug, model HC-810-P. This plug is designed for 1/2" tube outside diameter (OD) compression applications, offering a reliable seal in various industrial environments. Please read this manual thoroughly before using the product to ensure safe and efficient operation.
2. Safety Information
Always adhere to standard safety practices when handling and installing industrial components. Failure to follow these guidelines may result in injury, property damage, or product malfunction.
- Ensure the system is depressurized and drained before installation or maintenance.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Do not overtighten or undertighten fittings. Refer to installation instructions for proper torque specifications.
- Verify material compatibility with the system fluid and operating conditions.
- Keep the product clean and free from contaminants.
3. Product Overview and Components
The Swagelok Alloy C-276 Plug is a robust fitting designed to seal off the end of a 1/2" OD tube line. It consists of a main body with a hexagonal shape for wrenching, and an internal compression mechanism.

Key components include:
- Plug Body: The main hexagonal component that houses the sealing mechanism.
- Nut: (Not explicitly shown as separate, but implied in compression fittings) Secures the plug to the tube fitting.
- Ferrules: (Not explicitly shown as separate, but implied in compression fittings) Front and back ferrules create the seal and grip on the tube.
4. Setup and Installation
Proper installation is crucial for leak-tight performance. Follow these steps carefully:
- Prepare the Tube: Ensure the 1/2" OD tube end is cut squarely, deburred, and free of scratches or defects.
- Insert the Plug: Insert the plug into the Swagelok tube fitting body until it bottoms out.
- Finger Tighten: Finger tighten the nut onto the fitting body.
- Wrench Tighten: Mark the nut at the 6 o'clock position. Tighten the nut 1/4 turn with a wrench. For larger sizes (1" and above), 1/4 turn plus 1/8 turn may be required. Consult Swagelok's official installation guides for precise torque specifications if available for this specific plug type.
- Inspect: Visually inspect the connection to ensure the nut is properly seated and the plug is secure.
Note: For critical applications or if unsure, always refer to official Swagelok installation procedures and training resources.
5. Operating Principles
The Swagelok Alloy C-276 Plug functions by creating a mechanical seal against the internal components of a Swagelok tube fitting. When the nut is tightened, the ferrules are driven forward, with the front ferrule creating a primary seal on the fitting body and the back ferrule providing a secondary seal and gripping the tube (or in this case, the plug itself) securely. The Alloy C-276 material provides excellent corrosion resistance in harsh environments.
6. Maintenance
The Swagelok Alloy C-276 Plug is designed for long-term, reliable service with minimal maintenance. However, periodic inspection is recommended.
- Visual Inspection: Regularly check for any signs of corrosion, damage, or leaks around the fitting.
- Cleaning: If necessary, clean the exterior of the plug with a mild detergent and water. Avoid abrasive cleaners.
- Re-tightening: If a leak is detected, a slight re-tightening (1/8 turn) may resolve it. Do not overtighten. If the leak persists, the fitting may need to be disassembled, inspected, and potentially replaced.
- Replacement: If the plug or associated fitting components show significant wear, damage, or cannot maintain a seal, replace them with genuine Swagelok parts.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leak at the fitting connection | Insufficient tightening, damaged ferrules, improper tube preparation, or contaminated components. | Slightly re-tighten the nut (1/8 turn). If leak persists, depressurize, disassemble, inspect components for damage, clean, re-cut tube if necessary, and reassemble. Replace damaged parts. |
| Difficulty tightening the nut | Cross-threading, damaged threads, or incorrect component alignment. | Ensure proper alignment before tightening. Do not force. Inspect threads for damage. Replace if threads are stripped or damaged. |
| Corrosion on plug surface | Exposure to incompatible chemicals or harsh environmental conditions beyond material limits. | Verify material compatibility for the application. Clean regularly. If corrosion is severe, replace the plug. |
