Racewill 25 ft 3/16" Copper-Coated Brake Line Kit with 16 Fittings, 4 Unions & Flaring Tool

Racewill 25 ft 3/16" copper-coated brake line kit delivers corrosion-resistant tubing, a full set of brass fittings and unions, plus a double and single flaring tool to make professional-quality brake and fuel lines at home.

This kit bundles 25 feet of flexible 3/16" copper-coated steel brake line with a comprehensive assortment of brass fittings and unions, plus a manual flaring tool that handles both single and double flares. It’s designed for DIY vehicle repairs, restorations, and custom plumbing of hydraulic, fuel, and transmission lines where durability and airtight flares matter. The copper coating improves corrosion resistance while keeping the tubing pliable enough to bend and flare with basic hand tools.

How durable and weather-resistant is the copper-coated tubing?

The copper layer protects the steel core from rust and extends service life versus bare steel lines, especially in wet or salty climates. The material remains formable so you can route lines without kinking.

• Copper-coated steel for enhanced corrosion protection
• Pliable enough to bend by hand for custom routing
• Suitable for road salt, humidity and general exposure

What fittings and unions are included, and how do they fit my system?

This kit contains a wide variety of inverted tube nuts and threaded unions to connect to common brake, fuel, and hydraulic components. Brass construction resists rust and provides reliable sealing when properly flared and tightened.

• Assorted inverted tube nuts in common thread sizes for 3/16" tubing
• Multiple threaded unions to join runs or extend line length
• Brass fittings plated to resist corrosion and galling

Can I make both single and double flares with the included tool?

Yes — the flaring tool is built to produce single and double flares on soft metal tubing types, so you can match factory-style double flares or single flares where needed. It accepts standard O.D. tubing sizes used in brake and fuel lines.

• Works for double and single flares on 3/16", 1/4", 5/16", 3/8", 1/2" tubing
• Compatible with copper, aluminum, brass, magnesium, and soft steel
• Manual clamp and cone design for consistent flare formation

How easy is installation for a hobbyist or home mechanic?

The kit is designed to be approachable for experienced DIYers and competent home mechanics. With the flexible tubing and clear-fitting assortment you can cut, bend, flare and assemble runs without specialized factory equipment.

• 25 ft length covers many repair and reroute needs
• Tubing bends by hand; requires only common hand tools to finish
• Brass fittings thread smoothly and resist seizing

Who is this for: This Racewill kit is aimed at do-it-yourself mechanics, automotive restorers, small repair shops, and anyone building or replacing brake, fuel, or hydraulic lines who wants corrosion-resistant tubing, a broad selection of brass fittings, and a reliable manual flaring tool. It’s especially useful for projects in corrosive environments or for custom-routing where flexibility and dependable flares are essential.
