Our brake line couplers are praised for their reasonable price, high quality and practicality. Many customers find them useful for custom brake line works and updating brake systems. Their ease of installation is noted as a significant advantage. A comparison to local auto parts store finds our product to be more cost-effective. Some reported issues with leaks and difficulty of use with double flared tubing, however, many say these couplers are ideal in terms of build and application, making it a frequent recommendation among automotive enthusiasts and professionals.

These couplers worked great!
1. I used the couplers to connect brake lines together to get the length I needed. 2.You only have to use standard tools to get the job done. 3. Sometimes I would round the corners of the couplers, but, only on the ones where the coupling was in a hard position to reach with a straight combination wrench.

leaked
Was using with 45 degree double flared tubing and could not get these fittings to stop leaking. Even reflaring the tubing didn't work. Tightned one so much to stop leakage, I stripped the threads in the union coupler. Bought a replacement set @ my local auto supplier that were heavier (needed to use a 12 mm wrench on them compared to 7/16" on these) The new ones appeared to have a slightly larger center hole and a bigger flared surface inside. Installed them and had no leakage.
