Why You Need This Kit

Metric brake ports and tubing require exact-match threads to prevent leaks and cross-threading. Instead of sourcing each fitting separately, this 9-piece kit gives you the core metric sizes in one place—tube nuts to secure flares, inline unions to join lengths, and adapters to interface with SAE 3/16″ lines. Machined from marine-grade alloy for outstanding corrosion resistance, these fittings stand up to salt, moisture, and brake-fluid vapors, ensuring reliable, maintenance-free performance on every imported or metric-platform project.
