What are AN fittings?

AN fittings are a type of compression fitting used in the automotive industry to connect hoses and other components. These fittings come in a variety of sizes, and their sizes are designated by a number that represents the outside diameter of the hose the fitting is designed to work with. This number is often referred to as the AN size, and it can be a little confusing for those who are new to using AN fittings.

Luckily, there is an AN fitting hose size chart that can help you determine the correct size fitting for your application. Simply match the AN size of your hose with the AN size of the fitting you need, and you’ll be good to go. Whether you’re building a race car or just need to replace a damaged hose, AN fittings are a great choice for a secure and reliable connection.

Explanation of AN sizing system

AN fittings are a type of tubing fitting that have become the standard in the racing industry due to their high-performance capabilities. The AN sizing system was originally developed by the U.S.

military for use in aircraft and has now been adopted for use in automotive and racing applications. The AN sizing system uses a numbering system to indicate the size of the fitting based on the outside diameter of the tubing it is designed to fit onto. For example, AN-6 fittings are designed to fit onto tubing with an outside diameter of 3/8”.

In addition to the size designation, AN fittings also come in various angles and configurations to suit different plumbing needs. AN fittings are extremely reliable and can withstand high temperatures and pressures, making them a popular choice among racers looking for a durable and effective tubing fitting solution.

Size chart for AN fittings and hoses

If you’re new to the world of AN fittings and hoses, you might be feeling a bit overwhelmed with all the different sizes and terminology. But fear not, as we have put together an AN fitting hose size chart table to make things easier for you! AN fittings are measured in sixteenths of an inch, with the size referring to the outside diameter of the hose. So, for example, a -6 AN fitting would fit a hose with an outside diameter of 6/16th’s of an inch, or 3/8″.

It’s important to note that AN fittings and hoses are not interchangeable with regular fittings and hoses, as they are designed to withstand higher pressure and are manufactured to closer tolerances. So, always make sure to use the correct AN size for your application. Take a look at our AN fitting hose size chart table below to help you navigate the world of AN fittings and hoses with ease!

Tips for reading and using the chart

If you’re working on your car or motorcycle, using the right hose and fittings is crucial. An AN fitting hose size chart is a valuable tool that can help you select the proper size and type of hose and fitting for your project. However, understanding how to read and use the chart properly is essential.

First, you need to understand that AN stands for Army-Navy, and it is a military specification for fluid connections. It uses a sizing system that is based on the outside diameter of the hose rather than the inside diameter. The AN size typically ranges from -2 to -32, with larger numbers indicating a larger hose.

When using the AN fitting hose size chart table, start by finding the AN size of the hose you need. Then, look across the chart to find the corresponding dash size and fitting size. It’s important to note that different types of fittings have different thread sizes, so make sure you choose the correct size for your particular fitting and hose.

Another important consideration is the type of hose you’ll be using. There are different materials and constructions available, each with its own benefits and drawbacks. For example, stainless steel braided hose is durable and resistant to heat, but it is also quite expensive.

On the other hand, nylon braided hose is more affordable but may not be as durable in certain applications. In conclusion, using an AN fitting hose size chart can be a useful tool in selecting the correct hose and fittings for your project. However, it’s essential to understand how to read and use the chart correctly, choose the appropriate fitting size and material, and select the right type of hose for your particular application.

With these tips, you’ll be able to confidently choose the right hose and fittings for your car or motorcycle project.

Common applications for each size

AN fitting hose size chart AN fittings are commonly used in racing and high-performance automotive industries for hydraulic lines, fuel systems, and oil coolers. Understanding the different sizes of these fittings can be confusing, so referring to an AN fitting hose size chart table can help simplify the process. The main sizes for AN fittings range from -2 to -32, with -2 being the smallest and -32 being the largest.

Each size has its unique application depending on the fluid being transported, and the pressure and flow rate required. For example, the smaller -2 and -3 sizes are typically used for brake and clutch lines, while the larger -20 to -32 sizes are used for fuel lines and transmission coolers. It’s important to refer to a size chart to ensure that the correct fitting and hose size is selected for the proper application.

Choosing the right hose for your needs

When it comes to choosing the right hose for your needs, understanding AN fitting hose size chart is crucial. AN fittings are widely used in the automotive industry for their reliability and ease of installation. The AN fitting sizes are based on the outer diameter of the hose, which can range from -4 (1/4″) to -20 (1-1/4″).

It’s important to choose the right size for your hoses to ensure a secure fit and avoid leaks. Additionally, it’s crucial to consider the type of hose material, such as braided stainless steel or nylon, and the intended application. For high-pressure applications, stainless steel hoses are preferred for their durability and resistance to corrosion.

Nylon hoses, on the other hand, are more flexible and ideal for low-pressure applications. By understanding AN fitting hose size chart and selecting the appropriate hose material, you can ensure that your hoses will perform optimally and provide reliable, leak-free performance.

Factors to consider when selecting a hose

When selecting a hose, there are several factors to consider in order to choose the right one for your needs. Firstly, you should consider the type of material the hose is made from, as this will affect its durability and ability to handle specific temperatures and pressures. Additionally, the type of fitting required for your application should be taken into account, as well as the length and diameter of the hose.

These factors will determine the maximum flow rate and pressure the hose can handle, and therefore ensure that it meets your requirements. It’s also important to consider the specific application the hose will be used for, as this can impact the type of hose required. For example, if the hose will be used for a chemical transfer, you would need to choose a hose that is resistant to those chemicals.

Ultimately, selecting the right hose is crucial for ensuring safe and efficient operation, and it’s important to carefully consider these factors to make the best decision for your needs.

Typical uses for different hose materials

When it comes to choosing the right hose for your needs, it is important to consider the materials of the hose. Different hose materials have different properties that make them suitable for specific applications. For instance, rubber hoses are commonly used for air and water applications because they can withstand high pressure and are resistant to abrasion and weathering.

On the other hand, PVC hoses are lightweight, flexible, and resistant to kinks, making them ideal for a variety of watering and irrigation uses. Chemical-resistant hoses made of materials such as Teflon or Viton are perfect for transporting chemicals that would otherwise damage other types of hoses. Lastly, stainless steel hoses are highly durable and can withstand extreme temperatures and pressures, making them ideal for use in high-temperature applications such as steam cleaning.

When selecting a hose, consider the type of application you need it for and choose a material that will best suit your needs.

What Are the Different Applications for High Voltage Cables Compared to Regular Hoses?

When comparing high voltage cables to regular hoses, the high voltage cable size chart is crucial for determining the appropriate size and capacity for specific applications. High voltage cables are typically used in power transmission and distribution, while regular hoses are used for conveying fluids and gases in various industries.
