Compression fittings are widely used in many industries, including automotive. They are often used to repair brake lines because they provide a strong, permanent connection that can withstand high pressures. To repair a brake line with a compression fitting, first cut the damaged section of pipe out and clean the ends of the remaining pipe.

Next, slide the compression nut over one end of the pipe and thread it onto the other end. Then, tighten the nut until it is snug against the pipe. Finally, test your repair by bleeding the brakes and checking for leaks.

  • Begin by removing the old compression fitting from the brake line
  • To do this, use a small wrench or pliers to loosen the nut on the fitting
  • Once loose, pull the tubing out of the fitting
  • Cut a new piece of tubing to replace the old one using a pipe cutter
  • Make sure that the new piece is exactly the same length as the old one
  • Insert the new piece of tubing into the compression fitting and tighten down the nut with your wrench or pliers
  • Bleed your brakes according to manufacturer’s instructions and you’re finished!

3/16 Compression Fitting for Brake Line

If your vehicle has 3/16″ brake line, you’ll need a 3/16″ compression fitting to make the connection. This type of fitting is easy to use and doesn’t require any special tools. Simply insert the end of the brake line into the fitting and tighten the nut until it’s snug.

You can then connect the other end of the brake line to another piece of tubing or a component in your braking system. Compression fittings are very strong and provide a leak-free connection. They’re also reusable, so if you ever need to disconnect or repair your brake lines, you can simply unscrew the fitting and reconnect it when you’re finished.

What States is It Illegal to Use Compression Fittings on Brake Lines

Most states have laws that require brake lines to be made of a certain material and forbids the use of compression fittings. The reason for this is because compression fittings are not as strong as other types of fittings, and they can leak. If a brake line leaks, it can cause the brakes to fail.

Brake Line Compression Fitting Leaking

If you own a car, you know that one of the most important parts of the vehicle is the brakes. The brakes are what allow you to slow down and stop your car, so it’s vital that they’re in good working order. One problem that can occur with brakes is a brake line compression fitting leaking.

This can happen for a number of reasons, but fortunately it’s usually an easy fix. The first thing you’ll need to do if you think your brake line compression fitting is leaking is to check the fluid level in your brake reservoir. If the fluid level is low, then it’s likely that there is a leak somewhere in the system.

Once you’ve confirmed that there is a leak, locate the compression fitting on your brake line. This is typically located near the caliper or wheel cylinder. Once you’ve found the compression fitting, use a wrench to loosen it slightly.

You don’t want to remove it completely, just loosen it enough so that you can see inside. Inspect the o-ring on the compression fitting and look for any damage such as cracks or nicks. If the o-ring looks damaged, replace it with a new one before tightening the compression fitting back up again.

If your o-ring looks fine but you’re still seeing leaks, then there may be an issue with the threads on either the compression fitting or brake line itself.
