VKQTS Brake Line Kit — 25 ft 3/16" & 1/4" Copper-Plated Tubing with 32 Inverted Fittings and Single/Double Flare Tool

VKQTS 25ft Brake Line Kit is a complete brake-line repair and flaring set that includes 25 ft of 3/16" and 25 ft of 1/4" copper-plated steel tubing, 32 inverted fittings, and a single/double flare tool kit in a blow-molded case.

This all-in-one kit supplies the tubing, fittings and tools needed to cut, single-flare and double-flare brake lines for most passenger vehicles. Designed for home mechanics and professional technicians who want a compact, organized solution, the kit groups adapters, a tube cutter, flaring cone and yoke, and a selection of inverted nuts for fast field or garage repairs.

What components are included and what sizes do they fit?

The kit contains two 25 ft coils of copper-plated carbon steel brake line in 3/16" and 1/4" diameters, plus a full set of inverted tube nuts and adapters to match common vehicle fittings. A blow-molded case holds the tube cutter, flaring rod (yoke), flaring cone, five adapters and the nuts for neat storage.

• Brake tubing: 25 ft of 3/16" and 25 ft of 1/4" (copper-plated carbon steel).
• Inverted nuts: 32 total across 3/16" and 1/4" sizes with common thread sizes (7/16-24, 1/2-20, 9/16-18, 3/8-24).
• Tools: tube cutter (fits OD 1/8"–5/8"), flaring cone, flaring rod (yoke), 5 adapters (3/16"–1/2").
• Packaging: blow-molded case for transport and storage.

How do single and double flares work with this kit?

The included flaring cone and adapters guide you to form single or double flares reliably. Follow the steps to clamp the tube, use the flaring cone for a single flare, and add the adapter-first sequence to create a double flare for higher-pressure connections.

• Single flare: position in flaring rod hole, align cone, and apply even pressure until the lip forms.
• Double flare: seat adapter, form an initial flare, then re-flare to close and reinforce the flare.
• Tip: keep tubing straight and avoid over-extracting the tube from the rod for consistent flares.

Which vehicles and systems can this kit service?

This brake line kit is suited to many road cars, SUVs and light trucks that use 3/16" and 1/4" brake line sizes, and works on hydraulic braking and transmission lines where those diameters are used. The range of inverted nuts and adapters covers typical thread sizes found in domestic and many import vehicles.

• Common uses: brake line repairs, replacement sections, hard line splices and custom routing.
• Compatible with: most passenger vehicles and light-duty trucks using 3/16" or 1/4" lines.
• Not for: heavy commercial, high-pressure hydraulic systems beyond rated fitting sizes—verify vehicle specs before use.

What materials and durability features does the VKQTS kit offer?

The tubing is carbon steel with a copper-plated finish for corrosion resistance and strength; flaring tools are made from steel and iron to withstand the pressure of forming flares. Components are sized and organized to resist wear and remain serviceable through repeated use.

• Tube: carbon steel, copper-plated for rust resistance and longevity.
• Tools: steel/iron construction to handle repeated single and double flaring operations.
• Storage: blow-molded case prevents tool damage and keeps fittings sorted for quick access.

Who is this for: The VKQTS 25ft Brake Line Kit is built for DIY mechanics, restoration shops and technicians who want a ready-to-use brake line solution. It’s ideal if you need sufficient tubing for multiple repairs, a broad selection of inverted nuts and the ability to perform both single and double flares without buying separate tools. Always follow vehicle manufacturer torque and installation specifications and have brake work inspected or pressure-tested before regular driving.
