Racewill 25FT 3/16in Copper-Coated Brake Line Kit with Tube Bender & 20 Brass Fittings, Corrosion-Resistant

Racewill 25FT 3/16" copper-coated brake line kit supplies corrosion-resistant tubing, a manual tube bender, and a full set of fittings to replace or extend vehicle brake lines.

This kit bundles 25 feet of 3/16" copper-coated steel brake line with an upgraded selection of 20 brass fittings and a hand tube bender so you can cut, bend, and flare lines for most domestic and import brake systems. The copper coating protects the steel core against rust, while the included fittings and flaring compatibility let you assemble reliable connections without expensive shop visits.

What components are included in the Racewill brake line kit?

The kit arrives with a 25-foot length of 3/16" copper-coated steel brake tubing, a compact tube bender sized for common outer diameters, and twenty brass fittings plated to resist corrosion. Fittings cover popular inverted nut and union thread sizes to match a wide range of brake line ends.

• 25 ft of 3/16" (OD) copper-coated steel brake tubing, ready to cut and flare.
• 1 hand tube bender for 1/8", 3/16", and 1/4" tubing diameters.
• 20 brass fittings: multiple inverted tube nuts (7/16-24, 3/8-24, 1/2-20, 9/16-18) and unions for 3/8-24 threads.
• Plated brass hardware to reduce galvanic corrosion and improve longevity.

How does copper coating improve brake line durability?

Copper coating over a steel core combines the mechanical strength of steel with copper’s corrosion resistance. This finish slows rust formation compared with bare steel, extending service life in wet or salty environments while remaining pliable enough for hand bending and flaring.

• Coating prevents direct exposure of steel to moisture and salt.
• Retains tube flexibility for routing without kinking when bent properly.
• Better suited to harsh climates than uncoated steel tubing.

Can I flare and adapt these lines to my brake fittings?

Yes. The Racewill tubing supports single and double flares and works with common soft metals like copper, aluminum, brass, magnesium, and mild steel. The included brass fittings cover many inverted nut thread sizes and unions, simplifying adaptation to factory or aftermarket components.

• Compatible with single and double flare methods for secure seals.
• Brass fittings resist rust and are plated for extra corrosion protection.
• Flaring capability accommodates 1/2", 3/8", 5/16", 1/4", and 3/16" O.D. tubing.

How does the tube bender help during installation?

The included tube bender lets you form smooth, spring-back-minimized curves without collapsing the tubing, making on-vehicle routing faster and cleaner. Its caliper sizes match the kit’s tubing and common brake line diameters used in repairs and custom runs.

• Fits 1/8", 3/16", and 1/4" outer diameter tubing for precise bends.
• Reduces need for hammering or repeated adjustments while installing.
• Helps avoid kinks and preserves internal bore for reliable fluid flow.

Who is this for: The Racewill 25FT 3/16" copper-coated brake line kit is aimed at DIY mechanics, restoration builders, and professional technicians who need a long, corrosion-resistant run of brake tube plus a broad assortment of fittings and a manual bender. It’s particularly useful for vehicles exposed to road salt or coastal conditions, custom brake routing, or projects where replacing multiple sections of line is necessary. If you require specialized OEM thread types or stainless lines for very high-pressure race applications, verify thread compatibility or consider a stainless alternative.
