Brake Nuts & Adapters

Our range of brake nuts and adapters is designed for secure connection of hydraulic brake pipe systems in automotive and engineering applications. Available in metric, UNF and BSF thread forms, these components are suitable for classic vehicle restoration, workshop repairs and motorsport use.

Manufactured for accurate thread engagement and reliable sealing under pressure, our brake nuts and brake line adapters ensure safe and consistent brake system performance. We stock common sizes for 3/16" and 1/4" brake pipe installations, including metric fine and imperial thread options.

For complete brake line installations, pair these fittings with our high-quality "brake tubing" , or explore related hydraulic components within our "brake fittings and hydraulic brake line components" range.
