Corrosion-resistant connections - with plated brass construction

Quality brass bodies are plated to add a protective layer that slows oxidation and surface corrosion. The plating adheres to brass surfaces to reduce direct metal exposure to moisture and road salts.

Fewer corroded joints over time leads to less maintenance and a lower risk of leaks. Durable finish keeps fittings serviceable during routine vehicle use.

Secure joins for standard lines - with metric invert flare sizing

Metric invert flare geometry and 3/8 inch thread form a mechanical seal when tightened onto 3/16 inch brake line tubing. Designed to work with both inverted flare and double flare connection types.

Reliable mechanical seals make joining or extending brake lines straightforward for repair tasks. Consistent sizing reduces the chance of mismatched fittings during replacement.

Pack contains ten identical fittings, providing multiple spares for common repair scenarios or to keep in a workshop kit. Quantity supports replacing several joints without sourcing individual parts.

Carrying a handful of spares simplifies roadside fixes and scheduled maintenance. Multiple pieces mean fewer trips to suppliers during small repair jobs.
