Ailbiuko 3/16" Brake Line Tubing Kit, 2x25 ft Copper-Plated Tubes with 60 Fittings (Inverted‑Flare)

The Ailbiuko 3/16" Brake Line Tubing Kit supplies two 25-foot copper‑plated brake tubes and 60 assorted inverted‑flare fittings for repairing or extending automotive brake, fuel, and hydraulic lines.

This all-inclusive kit is built for DIY mechanics and professional technicians who need corrosion‑resistant tubing and a wide selection of fitting sizes to match common inverted and double‑flare connections. The copper‑plated tubing offers improved flexibility and rust protection, while the assortment of unions and nuts covers typical thread standards so you can splice, extend, or replace 3/16" lines without sourcing multiple parts separately.

What components are included and why they matter?

The kit contains two 25‑foot lengths of 3/16" tubing plus 60 fittings in four thread sizes and unions to join lines. Having the correct mix of nuts and unions prevents repeated trips to the parts store and helps complete a repair with the right thread match.

• 2 x 25 ft 3/16" copper‑plated brake tubes for routing and replacement.
• 40 pieces of 3/16" (3/8‑24) inverted tube nuts for common connections.
• 6 pieces of 3/16" (7/16‑24), 4 pieces of 3/16" (1/2‑20), 4 pieces of 3/16" (9/16‑18) inverted nuts for varied thread matches.
• 4 x 3/16" (3/8‑24) inverted tube unions to join two brake lines securely.

How does the copper plating affect performance and longevity?

Copper plating adds a corrosion barrier and improves tube ductility compared with untreated steel, making bending and routing easier during installation. While not a guarantee of infinite life, the plating helps resist pitting and surface rust in harsh environments.

• Enhanced corrosion resistance versus plain steel tubing.
• Smoother surface reduces abrasion where tubing contacts clamps and fittings.
• Improved bendability for routing through tight engine bays and chassis.

Which vehicles and systems will this kit fit?

The kit is designed primarily for 3/16" brake lines using inverted or double‑flare fittings and commonly suits cars, trucks, and SUVs. It also works for low‑pressure fuel and hydraulic lines where 3/16" tubing and the listed thread sizes are specified.

• Compatible with most 3/16" inverted‑flare brake line applications.
• Usable for fuel lines and some hydraulic systems with matching fittings.
• Thread sizes included cover a broad range of domestic and import vehicles.

How simple is installation and what tools are needed?

Installation is straightforward: clean tube ends, slide on nuts, align tubing, install the union, and tighten. A standard flare wrench set and tube cutter/bender make the process faster and help avoid leaks or damaged fittings.

• Tools recommended: tubing cutter, tube bender, flare or line wrenches, and a torque‑appropriate wrench.
• Prep tip: deburr cut ends and wipe surfaces clean before assembly to ensure a proper seal.
• Union connectors allow joining two tubes quickly without flaring modifications.

Who is this for? The Ailbiuko 3/16" Brake Line Tubing Kit is ideal for home mechanics, restoration shops, fleet maintenance teams, and anyone who regularly services brake or fuel lines and wants a ready assortment of tubing and fittings. It’s especially useful when working on older vehicles or custom brake routing where matching multiple thread sizes and having extra length on hand can save time and avoid delays.
