Ailbiuko Brake Line Tubing Kit 3/16" & 1/4", 25FT Copper-Plated with 60 Fittings

Ailbiuko's kit supplies 25 feet of copper-plated 3/16" and 1/4" brake tubing plus 60 assorted inverted-flare fittings for reliable, corrosion-resistant brake and fuel line repairs.

This comprehensive brake line tubing set bundles two common tube diameters with a full assortment of inverted-tube nuts and unions so you can cut, join and route lines for cars, trucks and SUVs without multiple trips to the parts store. The tubing is copper-plated and treated to resist corrosion while remaining formable for bends and flares. Each fitting size is included to match standard 3/16" and 1/4" applications, letting you assemble or repair brake and fuel runs on a variety of vehicles.

What exactly comes in this Ailbiuko tubing and fitting kit?

The kit includes two continuous brake tubes (one 3/16", one 1/4") totaling 25 feet and sixty fittings in multiple thread sizes. Fittings are provided as inverted tube nuts and unions to join, extend, or repair existing brake lines without special adapters.

• 1 x 3/16" tube and 1 x 1/4" tube (total 25 feet)
• Multiple inverted tube nuts: 3/8-24, 7/16-24, 1/2-20, 9/16-18
• Inverted tube unions to connect two tube ends securely
• 60 total pieces covering common brake/fuel system thread patterns

How does the copper plating help for automotive brake work?

Copper plating over the base tubing enhances corrosion resistance and keeps lines flexible for bending and flaring during installation. That treatment reduces the chance of surface rust that can complicate future repairs and provides a smoother surface for making reliable inverted-flare connections.

• Corrosion-resistant surface treatment for longer life
• Good flexibility for clean bends and flares
• Smoother flare seating compared with untreated steel

Which vehicles and systems can I use this kit on?

The kit is sized for standard inverted/double-flare 3/16" and 1/4" brake tubing applications and works well on many cars, light trucks and SUVs. Beyond brakes, the fittings and tubing are compatible with fuel and general hydraulic lines where these diameters and thread patterns are appropriate.

• Common passenger vehicles and light trucks
• Brake line repairs, replacements, or extensions
• Fuel lines and other low-pressure hydraulic connections

How do I join two brake lines using the included fittings?

Joining two brake tubes is straightforward: clean both tube ends, slide on the matching nuts, insert the tubes into the union, then tighten the union with a wrench to form a secure inverted flare connection. Ensure threads match and torque appropriately to avoid leaks; always follow vehicle safety procedures.

• Clean tube ends before assembly
• Use the matched-size inverted nuts and unions provided
• Tighten with a wrench until properly seated—check for leaks

Who is this kit best suited for? This Ailbiuko brake line kit is designed for DIY mechanics, restoration hobbyists and professional technicians who need an all-in-one solution for 3/16" and 1/4" tubing jobs. It’s ideal when you want flexibility on the workbench or on the vehicle—whether repairing a rusted section, extending a run, or fabricating new lines. The selection of thread sizes and unions makes it a practical choice for garages that service multiple vehicle makes and for anyone who prefers to carry a comprehensive set of fittings for on-the-spot repairs.
