What size thread for 3/16 brake line?
When it comes to maintaining your vehicle, understanding the specifications of various components is crucial. One such component is the brake line, particularly when dealing with 316 stainless steel brake lines. In this article, we will explore the appropriate thread size for 316 brake lines, ensuring you have the right information for your next auto repair or maintenance task.
What is a 316 Brake Line?
316 brake lines are made from a type of stainless steel known for its corrosion resistance and durability. This makes them an excellent choice for automotive applications, especially in environments where moisture and road salt can lead to rust and degradation of standard steel lines.
Thread Size for 316 Brake Lines
The thread size for 316 brake lines typically follows standard automotive specifications. Most commonly, you will encounter:
- 1/8 inch NPT (National Pipe Thread) - This is a standard size used for many brake line fittings.
- 3/16 inch brake line fittings - These are often used in conjunction with the 1/8 inch NPT threads.
It is essential to ensure that the fittings you choose match the thread size of your brake lines to avoid leaks and ensure a secure connection.
Why Proper Thread Size Matters
Using the correct thread size is vital for several reasons:
- Safety: Properly threaded connections prevent brake fluid leaks, which can lead to brake failure.
- Performance: Ensures optimal brake performance by maintaining hydraulic pressure.
- Durability: Correct fittings reduce wear and tear on the brake line and associated components.
Conclusion
In summary, when working with 316 brake lines, it is crucial to use the correct thread size, typically 1/8 inch NPT. This ensures safety, performance, and durability of your vehicle's braking system. If you have any doubts or need assistance, don't hesitate to consult a professional mechanic or visit your local auto service center.
Frequently Asked Questions
Should I use 3/16 or 1/4 in brake line?
When a replacement line is needed, the obvious question is what size brake line to get. The answer is really pretty easy. Almost every car or truck worldwide utilizes a 3/16-inch brake line, also referred to as a CNF-3.
What type of fittings are used on brake lines?
Here are the most common types:
- Double Flare Fittings: These are widely used in automotive brake systems.
- Bubble Flare Fittings: Bubble flare fittings, also known as single flare fittings, are commonly found in European vehicles.
- AN (Army-Navy) Fittings: AN fittings are used in racing and high-performance applications.
What is bigger, 3 16 or 1/4?
But now with the same denominator. We're just going to compare the numerators. And 4 is larger than 3 so 4 16 that's larger than 3 16. And therefore one-fourth that is larger than 3 16..
How to measure 3/16 brake line?
You can also use a 1/4" open end wrench to gauge your lines. It will fit easily onto 1/4" line and will bang back and forth on 3/16" line. A stack of three pennies is about 3/16" thick and three pennies and a nickel are around 1/4" thick. On some late model GM and most European built cars the larger line will be 6mm (.

What size are copper brake lines?
Brake Pipe Characteristics:
This product is constructed from soft copper tubing and is suitable for use in braking automotive systems. It has an outer diameter of 3/16" / 4.76mm and a wall thickness of 0.028" / 0.71mm.
What size threads are on a 3/16 brake line?
Imperial Sizes:
| Line Size | Outer Diameter (OD) | Thread Pitch |
|---|---|---|
| 3/16" | 0.1875" | 24 TPI |
| 1/4" | 0.25" | 24 TPI |
What thread size are brake lines?
Normally, a 7/16 fine thread is 7/16-20. The threads for 1/4" brake lines where a rubber hose screws into a wheel cylinder with a copper gasket ARE the 7/16-20 standard fine thread. 3/16" lines use standard 3/8-24 threads for both the flare nuts and the gasketed fittings.

Why are copper brake lines illegal?
The Society of Automotive Engineers determined the corrosive deterioration of the steel brake line was at fault. The industry switched to brake lines made from 100% copper. These lines burst from the pressure causing even more accidents. People demonized the copper brake lines.
