2. Safety Information
WARNING: Always wear appropriate personal protective equipment (PPE) such as safety glasses and gloves when handling and installing automotive components. Ensure the vehicle's system is depressurized and cooled before working on any fluid lines.
Image Description: A yellow triangle warning symbol followed by bold text stating: "WARNING: THIS PRODUCT CAN EXPOSE YOU TO CHEMICALS WHICH ARE KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER OR BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM. FOR MORE INFORMATION, VISIT WWW.P65WARNINGS.CA.GOV." This is a standard California Proposition 65 warning label.
Proposition 65 Warning: This product can expose you to chemicals which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information, visit www.P65Warnings.ca.gov.
Ensure all connections are secure and free from leaks before operating the vehicle. Improper installation can lead to fluid leaks, fire hazards, or other serious injuries.
3. Package Contents
Upon opening the package, verify that all components are present and undamaged. The package should contain:

4. Setup and Installation
This adapter fitting is designed for use in automotive fluid systems, typically fuel, oil, or coolant lines. Proper installation is critical for performance and safety.
Installation Steps:
- Preparation: Ensure the system is de-pressurized and cool. Clean the mating surfaces of both the hose end and the component where the NPT thread will connect. Remove any debris or old sealant.
- NPT Connection: Apply a suitable thread sealant (e.g., PTFE tape or liquid thread sealant compatible with the fluid) to the male 1/4" NPT threads of the adapter fitting. Carefully thread the NPT end into the component's female NPT port. Tighten securely using an appropriate wrench, but do not overtighten, as this can damage the threads or the component.
- AN Connection: Connect the female -6AN hose end to the male -6AN side of the adapter fitting. Ensure the 37-degree flare surfaces align perfectly. Hand-tighten the AN connection first, then use an AN wrench to tighten it to the manufacturer's recommended torque specifications for AN fittings. Avoid using standard open-end wrenches, which can damage the anodized finish and the fitting.
- Inspection: After installation, visually inspect all connections for proper seating and alignment.
- Leak Test: Once the system is re-pressurized, carefully check for any signs of leaks around the installed fitting. Address any leaks immediately before operating the vehicle.

5. Operating Principles
The Edelbrock/Russell 614206 adapter fitting serves as a crucial interface between two different thread standards: AN (Army-Navy) and NPT (National Pipe Taper). AN fittings are commonly used in high-performance automotive and aerospace applications due to their reliable sealing capabilities and ease of assembly/disassembly. NPT threads are a common standard for general-purpose piping.
The 37-degree flare on the AN side creates a metal-to-metal seal when compressed, ensuring a positive, leak-free connection for fluid transfer. The NPT side relies on tapered threads and a thread sealant to create a pressure-tight seal.
6. Maintenance
This adapter fitting is designed for durability and requires minimal maintenance. However, periodic inspection is recommended to ensure continued performance and safety.
- Visual Inspection: Regularly check the fitting for any signs of corrosion, damage, or leaks. The blue anodized finish helps protect the aluminum, but harsh chemicals or abrasion can compromise it.
- Cleaning: If cleaning is necessary, use a soft cloth and a mild, non-abrasive cleaner. Avoid harsh solvents or abrasive materials that could damage the anodized finish or the threads.
- Re-tightening: If any looseness or minor weeping is observed, carefully re-tighten the connections to the appropriate torque specifications. Do not overtighten.
7. Troubleshooting
Most issues related to adapter fittings stem from improper installation. Refer to the "Setup and Installation" section for detailed steps.
| Problem | Possible Cause | Solution |
|---|---|---|
| Fluid Leak at NPT Connection | Insufficient thread sealant; damaged threads; undertightened. | Disassemble, clean threads, reapply thread sealant, and re-tighten to proper torque. Inspect threads for damage. |
| Fluid Leak at AN Connection | Improperly seated flare; damaged flare surface; undertightened. | Disassemble, inspect flare surfaces for damage or debris. Ensure proper alignment and re-tighten to AN torque specifications. |
| Fitting feels loose after installation | Undertightened connections. | Carefully re-tighten both NPT and AN connections to their respective torque specifications. |
