If you’re into car tuning, racing or simply love tinkering with your engine, then you probably already know how vital AN fittings are to your project. These fittings are perfect for customizing and upgrading fuel lines, oil lines, and other essential parts of your engine system. However, choosing the right AN fitting tool can be a daunting task, especially if you don’t have any prior experience.
In this article, we’ll guide you through everything you need to know about AN fitting tools, including what they are, why they matter and how to choose the best one for your needs. So, let’s dive right in!
What Are AN Fittings?
AN fittings (short for Army-Navy) were initially designed for military purposes but later found their way into aerospace and motorsports applications due to their superior performance qualities. These fittings consist of a male (external) end and a female (internal) end that fit together with a 37-degree flare on each side. The flare angle ensures a leak-free seal between the two ends when tightened using an appropriate tool.
Why Do AN Fittings Matter?
AN fittings offer several advantages over traditional compression fittings or hose clamps. Firstly, they provide a more secure connection that won’t come loose under high-pressure conditions or vibrations. Secondly, they allow for more flexibility in routing hoses around tight spaces since they come in various angles and sizes. Finally, they offer a cleaner appearance since there’s no need for bulky clamps or zip ties.
Choosing the Right AN Fitting Tool
Now that we’ve established what AN fittings are and why they matter let’s talk about how to choose the right AN fitting tool for your project. Here are some factors to consider:
1. Type of Fitting
AN fittings come in different types such as straight, elbow, tee, Y-block, and bulkhead fittings. Each type serves a specific purpose, so it’s essential to choose the right one for your application. For instance, straight fittings are ideal for connecting hoses in a straight line, while elbow fittings work best when you need to route hoses around tight corners or angles.
2. Size
AN fittings come in different sizes ranging from -2 to -32. The size refers to the diameter of the fitting’s thread (not the hose) and determines the flow rate capacity of the fitting. It’s crucial to select the right size that matches both your hose and pump or regulator’s size.
3. Material
AN fittings can be made of various materials such as aluminum, stainless steel, brass, or plastic. Each material has its advantages and disadvantages in terms of weight, durability, cost, and corrosion resistance. Aluminum is lightweight but prone to cracking under extreme pressure conditions, while stainless steel is heavy but more durable and corrosion-resistant.
4. Quality
The quality of AN fitting tools varies greatly depending on the manufacturer. Some brands offer high-quality tools with precise tolerances that ensure a proper fit every time, while others offer lower-grade tools that may not perform as well or last as long. It’s always advisable to invest in high-quality tools from reputable brands like Earl’s Performance or Aeroquip to avoid any potential issues down the line.
5. Price
AN fitting tools come at different price points depending on their quality and brand. While it may be tempting to go for cheaper options, it’s essential to keep in mind that investing in higher quality tools will save you money in the long run by avoiding costly repairs or replacements.
Conclusion
Choosing the right AN fitting tool is crucial for ensuring a successful engine project or race day performance. By considering factors like type of fitting, size, material, quality, and price, you’ll be better equipped to make an informed decision that meets your needs and budget.
If you’re still unsure about which AN fitting tool to choose, consult with a professional mechanic or tuner for expert advice. With the right tools and knowledge, you’ll be able to take your engine performance to the next level!
