Ailbiuko 3/16" Brake Line Repair Kit — 100-Piece Fittings & 25 ft Copper-Plated Tubing, Flaring Tool

This kit is built for do-it-yourself mechanics and professional technicians who need a reliable assortment of fittings and tools to repair or extend 3/16" lines. It bundles a heavy-duty flaring tool that handles single and double flares, a tubing cutter and bender, and a generous length of corrosion-resistant tubing. The organized case and multiple thread sizes let you match fittings to a wide range of vehicles and systems without sourcing individual parts.

What components are included, and how are they organized?

The kit groups tools, fittings, and tubing in one compact box so you can get to work quickly. Fittings are sorted by thread size and the toolset stores neatly in the foam insert to reduce loss and damage.

• 1 flaring tool kit (flaring bar, cutter, cone, 5 adapters, bender)
• 25 feet of copper-plated 3/16" brake tubing
• 100-piece fitting assortment: multiple inverted nuts and unions in four thread sizes
• Storage box with compartments for fast access

How does the flaring tool work and what materials can it handle?

The included flaring tool performs both single and double flares to create secure, leak-resistant connections. It clamps the tubing, cuts squarely, and forms precise flares suitable for brake, fuel, and transmission lines.

• Supports copper, brass, aluminum, magnesium, and mild steel tubes
• Fits 3/16", 1/4", 5/16", 3/8" and 1/2" tubing sizes
• Includes adapters and a reaming tool to deburr and shape the tube end

Which thread sizes and fittings are supplied for 3/16" tubing?

The set contains common inverted nuts and union connectors to match factory brake fittings and aftermarket lines. Multiple thread patterns let you connect lines from different manufacturers without adapters.

• 3/8-24 inverted tube nuts and unions
• 7/16-24, 1/2-20, and 9/16-18 inverted tube nuts
• Unions included for joining two line ends securely

How do I install a connector on two brake lines?

Installation is straightforward: clean, position, and tighten. The kit includes a reamer to prepare tubing and nuts that thread to the union for a mechanical seal.

• Clean tube ends and remove any corrosion or paint
• Slide nuts onto each tube, then insert tube ends into the union
• Tighten both nuts with a wrench to compress the flare and secure the joint

Who this is for: The Ailbiuko 3/16" Brake Line Repair Kit is aimed at automotive DIYers, mobile mechanics, restoration shops, and anyone who services brake, fuel, or hydraulic lines. It suits projects where on-vehicle repairs, custom runs, or emergency field fixes are required. The kit’s selection of thread sizes and the multi-material flaring tool also make it useful for plumbing and small hydraulic repairs beyond strict automotive use, while the 25 feet of copper-plated tubing gives enough length for most common jobs without immediate reordering.
