The Stop Shop 45-Piece 3/16" Brake Line Fitting Assortment — Inverted Flare & Bubble/ISO, SAE & Metric, Corrosion-Resistant

This kit from The Stop Shop bundles the most commonly needed SAE and metric inverted-flare and bubble/ISO flare fittings for 3/16" brake tubing, saving time hunting down individual parts. Every fitting is coated to resist corrosion and organized in a compact pack so you can match thread types quickly on vintage and modern braking systems.

What specific fittings are included and how do I identify them?

The assortment includes a mix of SAE inverted-flare sizes and metric bubble/ISO flare sizes that cover typical 3/16" brake line applications. Each size is selected to fit common master cylinders, wheel cylinders, and flexible hose connectors.

• Inverted flare SAE: 12-3/8"-24, 3-7/16"-24, 2-9/16"-18, 2-1/2"-20.
• Inverted flare metric: 10-10x1mm.
• Bubble/ISO flare metric: 10-10x1mm, 2-11x1.5mm, 2-12x1mm, 2-13x1.5mm.
• Total count: 45 coated fittings ready for 3/16" brake tubing use.

How does the coating benefit the fittings during service?

The protective finish reduces rust and extends the usable life of fittings exposed to road moisture, salt, and brake fluid. Corrosion resistance helps maintain reliable sealing surfaces and reduces the chance of seizing during removal.

• Corrosion-resistant coating for longer service life.
• Preserves thread and flare integrity for better seals.
• Reduces need to replace fittings after short-term surface oxidation.

Can this assortment handle both metric and SAE connections on the same vehicle?

Yes — the kit includes common sizes from both standards so you can adapt to mixed-thread systems often found in older restorations or vehicles with replacement components. It’s designed specifically for 3/16" brake tubing, so you won’t need separate assortments for most jobs.

• Includes both inverted-flare (SAE) and bubble/ISO (metric) sizes.
• Useful for mixed-thread brake systems and retrofits.
• Ideal for on-the-spot repairs and parts-matching.

How should I use these fittings to ensure a safe, leak-free brake line connection?

Match the fitting type and thread to the component you’re joining, prepare the tubing end with a clean 45° or specified flare, and tighten to the torque recommended for the vehicle manufacturer. Inspect for leaks after pressurizing the system and re-torque if required.

• Verify inverted vs. bubble/ISO style before flaring tubing.
• Cut tubing square, deburr, and form the proper flare profile.
• Tighten to vehicle torque specs and check for leaks under pressure.

Who is this for: Mechanics, auto restorers, and DIY enthusiasts who work on 3/16" brake lines and need a reliable selection of both metric and SAE fittings. This 45-piece assortment is practical for mobile repair kits, shop drawers, and restoration projects where quick access to multiple thread sizes and flare types reduces downtime and avoids repeat trips to a parts counter.
