Brake Fitting Adaptors

A range of brake line fittings, adaptors, and connectors for building, modifying, or repairing brake and clutch hydraulic systems. Whether you're converting between metric and imperial thread sizes, adding a tee for a brake bias valve, or routing a hard line through a bulkhead, BRT Motorsport stocks the fittings you need.

Types Available

  • M10 x 1.0 fittings — standard metric brake line thread, used on most European vehicles
  • 3/8" UNF fittings — imperial thread size used on AP Racing and other performance brake components
  • Bulkhead fittings — for routing brake lines cleanly through panels and firewalls
  • Tee fittings — for splitting a single brake line into two, useful for bias valve and dual-circuit installations
  • Adaptors & converters — for connecting metric to imperial fittings or different thread standards
  • Stainless steel options — for corrosion resistance in performance and motorsport builds
