Before you install compression fittings on your brake line, you must know the DOT rules and specifications regarding brake lines. Depending on the type of brake line, you may need to check with your local DOT to confirm that the fittings are approved. You may also want to check the pressure rating of the fitting.

Can I Use Fittings For Brake Lines?
Compression fittings are a good choice for small water lines around the house but are not appropriate for brake lines. They’re designed for lower-pressure lines and are usually made of brass. They have five main components: a ferrule, a nut, two threaded pieces, and a seal. Brake lines are essential safety features, and drivers must ensure they’re working correctly to keep them safe. Brakes are a significant safety concern; failing to repair them correctly can result in severe consequences, including accidents. Brake failure is blamed in five percent of car accidents, so drivers must use their brakes correctly.
The use of compression fittings for brake lines is not widespread, but in some instances, it’s permissible. Compression fittings are cheaper than solder shut-off valves and are generally more reliable. However, you should check with your state’s laws to see whether these fittings are legal in your area. If you’re installing brake lines for a non-road vehicle, it’s best to use copper. Copper is easier to bend and replace than other materials.
On the other hand, PVF (polyvinyl fluoride) brake lines have a polyvinyl fluoride coating baked onto a galvanized steel line. This coating provides superior protection from rust. Compression fittings can be a better option for bending brake lines because they’re less likely to lose their grip on the tubing. They’re also generally more reliable than threaded fittings. Repeated bending can damage a threaded fitting, and you could lose your grip on the tube.
How Do You Install Compression Fitting On Brake Line?
There are a few essential steps that you should take when installing compression fittings on brake lines. First, ensure that you use the proper fit for the job. Some types of fittings cannot be used on other classes. For example, a double flare fitting cannot be installed on a union. If this is the case, you should get an adapter. If you’re replacing the brake line on your vehicle, you can use compression fittings to make the job easier.
These fittings are made for brake lines and are designed explicitly for them. However, be aware that you must consider the buyer’s actions when installing these fittings. Compression fittings are not the best choice for repairing brakes. The brake system is an essential safety feature on a vehicle. Its failure can result in accidents. Approximately 5 percent of automobile accidents are attributed to brake failure. Compression fittings should only be installed by a professional.
It would help if you were careful not to over-tighten compression fitting nuts. This can deform the ferrule and cause the joint to fail. Excessive vibration and internal fluid pressure can also damage them. For this reason, it’s best to use vibration-resistant fittings. Also, high-temperature fittings are available for temperatures between 215 degrees Fahrenheit and 450 degrees Fahrenheit.
First, you need to make sure that the brake line is straight. If it is double-flared, you should use a double-flare tubing vise. The tubing vise should be countersunk so that the fitting’s chamfer aligns with the die’s lower edge. Finally, you should apply brake fluid to the face of the dice. Another critical step in installing brake lines is ensuring that the bleeder valves are open. This step is essential because it can affect the total price of the repair. Fortunately, several commercial kits can help you with the job. Also, be sure to use special pliers to make the job easier.
Are Compression Fittings DOT Approved?
There are many different types of DOT-approved fittings. One example is compression fittings. These are commonly used in air brake lines, transmissions, and more. They’re compact and require no tools for installation. They can also be removed without causing damage to surrounding components. Compression fittings connect two pieces of tubing. They’re also used in the medical, laboratory, and food industries. They provide a secure connection and ensure that fluids won’t leak. They’re also easy to install and come in various sizes and configurations. Most importantly, they’re very safe to use.
Although they’re not DOT-approved for brake lines, they’re often acceptable for temporary repairs on off-road vehicles. This allows the owner to perform other maintenance and test acceleration in a closed environment. However, compression fittings are prohibited if the car is used in public transportation. Compression fittings often require retightening to stop leaks. This can crimp the tube and increase the risk of leaks. Additionally, these fittings can have different pressure ratings.
As such, you must understand which type you want for your vehicle. Compression fittings are also ideal for cars that aren’t used on public roads and don’t require high speeds. They also come in handy for vehicle restoration, such as when working on car restoration. Using a compression fitting can also save you money. This is especially true if you’re working with a fleet of vehicles.
How Much Pressure Can A Compression Fitting Hold?
The pressure they hold is a critical factor when it comes to brake lines. However, if you don’t know how much pressure these fittings can handle, you could end up with a disaster. The best way to ensure that these fittings hold enough pressure is to carefully read the manufacturer’s instructions. Compression fittings are made to fit around 15,000 psi. That’s significantly higher than the pressure brake lines typically experience. Manual brakes can operate at about 900 to 1,000psi (69 bar), while power-assisted brakes can reach as high as 1,400+ psi (96 bar). Compression fittings eliminate the need for flanged tubing and are quick and easy to install.
When installing brake lines, be sure to match the types of fittings. For example, a double-flare fitting cannot be used in a union or bubble-flare caliper. Fortunately, adapters allow you to switch between different fittings safely. Compression fittings vary in design from manufacturer to manufacturer, but they all have the same essential components. The body of a compression fitting consists of a compression nut and a ferrule. The tubing is inserted into the fitting’s end, and the nut compresses the ferrule onto the tubing.
Compression fittings are generally not used on passenger vehicles but are fine for off-road cars and temporary repairs. However, using them on public roads is illegal and may cause accidents. While they are cheap and convenient, they are not a long-term solution. Accidents cost more money than compression fittings themselves. When choosing a compression fitting for your brake lines, ensure the tubing is smooth and free of any roughness. Also, ensure that no extrusion lines could create a leak path past the ferrule.
And remember to choose a fitting that is symmetrical in diameter. Compression fittings can hold a lot of pressure. They are advertised as able to join tubing and have a lot of stress. However, their main feature is the measurement system that it uses. A compression fitting is a screw that clamps a flared end into a tube seat.
