6 AN Fittings FAQs
What is a 6 an fitting?
A 6 AN fitting is a standardized fluid fitting designed for high-performance applications, particularly in fuel, oil, and coolant systems.
The “6 AN” designation refers to its size, which corresponds to 6/16 of an inch, or 3/8 inch, though it’s important to note this is a nominal size and not a precise measurement of any single dimension. These fittings utilize a 37-degree flared connection, creating a robust, leak-free seal when mated with compatible tubing or hoses, and are known for their reliability and durability in demanding environments.
What size fuel line for 6AN fitting?
A 6AN fitting is typically used with a 3/8-inch (9.5mm) fuel line. However, it’s important to understand that “AN” sizes are nominal and don’t directly correlate to standard fractional measurements.
- Nominal Size: 6AN roughly corresponds to 6/16 of an inch, which is 3/8 inch.
- Actual Dimensions: The internal diameter of a 6AN fitting and the corresponding hose are designed to accommodate a flow rate suitable for 3/8-inch fuel lines.
- Application: 6AN fittings are commonly used in fuel systems requiring a moderate flow rate, such as those found in performance vehicles.
Therefore, while not an exact match, a 3/8-inch fuel line is the standard size used with 6AN fittings. Always double check the manufactures specifications to ensure proper fitment.
Is 3/8 the same as 6AN?
No, 3/8 inch and 6AN are not precisely the same, though they are related.
6AN refers to a standardized fitting size with a nominal dimension close to 3/8 inch, but it doesn’t directly translate to a precise 3/8-inch measurement of any specific component.
The AN system uses a different sizing convention, and while a 6AN fitting is commonly used with 3/8-inch lines, the actual dimensions can vary. It is important to look at the exact dimensions of the fitting to make sure it will meet your needs.
What's bigger, 6AN or 8AN?
8AN is larger than 6AN. The “AN” sizing system, while not a direct measurement in fractions of an inch, indicates relative size. Higher numbers signify larger fittings. Therefore, an 8AN fitting will have a larger internal diameter, larger threads, and a greater flow capacity than a 6AN fitting.
Essentially, 8AN is designed for applications requiring a higher volume of fluid flow compared to 6AN. This makes 8AN suitable for high-performance fuel systems, larger oil lines, or other applications where increased flow is essential.
What is the size of 6AN in mm?
It’s important to clarify that “6AN” is a nominal size, not a precise measurement. Therefore, there isn’t one definitive millimeter equivalent.
- Nominal Size: 6AN corresponds to 6/16 of an inch, which is 3/8 of an inch.
- Approximate Inner Diameter: The internal diameter of a 6AN fitting and hose is generally around 8.7mm to 9.5mm. This is the most relevant measurement for fluid flow.
- Thread Size: The thread size for a 6AN fitting is 9/16″-18, which translates to approximately 14.28mm in diameter.
Therefore, while the nominal size relates to 3/8 inch, the critical dimension for fluid flow (the inner diameter) is approximately 8.7mm to 9.5mm.
