3/16″ Metric Brake Line Fitting Assortment (9-Piece)

When you’re working on imported or metric-spec brake systems, having the right fittings on hand is essential. The 4LifetimeLines® 3/16″ Metric Brake Line Fitting Assortment delivers nine precision-machined, corrosion-resistant components—tube nuts, unions, and adapters—tailored to the most common metric thread pitches. Each piece is engineered to mate perfectly with properly flared 3/16″ tubing and metric ports, so you get leak-free, DOT-compliant connections without guesswork or mismatched threads.

What’s Included

M6×1.0 Tube Nut (1)

M8×1.0 Tube Nut (1)

M10×1.0 Tube Nut (1)

M6×1.0 Union (1)

M8×1.0 Union (1)

M10×1.0 Union (1)

M6×1.0 → SAE 3/16″ Adapter (1)

M8×1.0 → SAE 3/16″ Adapter (1)

M10×1.0 → SAE 3/16″ Adapter (1)

All nine fittings come in a compact tray for organized storage and quick selection.

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.

Ready to master metric brake-line fabrication? Add the 3/16″ Metric Brake Line Fitting Assortment (9-Piece) to your cart now and never hunt for the right fitting again.
