Capri Tools 3/16 in. Double Flaring Tool
This compact double flaring tool is designed to create high-quality 45-degree SAE double flares on 3/16″ tubing. It’s compatible with non-stainless steel, nickel, and copper tubing, making it suitable for typical brake line work. The tool’s portable design allows operation off the vehicle as well as in tight spots on or under a vehicle. It helps users produce clean, consistent flares with less effort, which can be crucial for brake line integrity and leak prevention.
Titan 51535 3/16-Inch Double Flaring Tool
The Titan 51535 model offers a dedicated 3/16″ double flaring solution with a removable handle and a positioning bolt for precise alignment. It supports 3/16″ steel and nickel-copper tubing and is designed to deliver a perfect inverted 45-degree SAE double flare. It’s not recommended for stainless steel tubing, and its compact form enables in-vehicle repairs in tight under-car spaces, minimizing the need for extensive disassembly.
Brake Line Flaring Tool Kit, 3/16″, 1/4″, 5/16″, 3/8″ and 1/2”
This versatile kit covers a broad range of applications, enabling 45-degree double or single flares in copper, aluminum, brass, and some soft steel. It includes a flaring cone, flaring bar, tube cutter, five adapters, and a blow-molded case for portability. The premium tool steel construction for the bar and yoke promises durability, while the chrome swivel reduces friction. However, it’s important to note compatibility limits with hard materials like stainless steel, and users should verify fit with their tubing before starting a flare.
Brake Line Flaring Tool Kit for 45 Degree Single, Double and Bubble Flares
The SEEKSELF tool kit offers 45-degree single, double, and bubble flare capabilities across 3/16″, 1/4″, 5/16″, 3/8″ and 4.75mm tubing. It’s designed for vise mounting, with clear safety instructions and a practical instruction manual. This setup is ideal for garage benches where a stable, fixed position improves flare accuracy. Pros include broad compatibility and multiple dies, while cons may involve learning the vise-mount method and ensuring the tool remains firmly clamped during use.
Lisle 33260 Flaring Tool
The Lisle 33260 specializes in single or double flares on 3/16″ and 1/4″ tubing. Its low-profile design lets technicians flare tubing in tight spaces, and the built-in vise assembly helps hold tubing securely without marring. This tool is well-suited for quick repairs in cramped areas, reducing movement that could compromise flare integrity. It’s a simple, dependable option for standard brake line work that prioritizes stability and ease of use.
Buying Guide: Key Purchase Considerations
Flare quality and material compatibility matter most. For 3/16″ brake lines, confirm whether the tool supports steel, nickel-copper, copper, or aluminum, and whether it handles softer or harder materials. Double flares are often preferred for brake lines due to better sealing, but single flares may suffice for certain applications. Look for a tool with a sturdy yoke, durable dies, and a reliable clamping mechanism to prevent tubing marring. Consider whether you need a portable off-vehicle tool, or a heavy-duty bench or vise-mounted kit for workshop use.
Ease of use is another priority. Tools with removable handles, precise alignment aids, or included lubricants can reduce effort and improve consistency. If you work on vehicles in tight spaces, a compact design and a tool that works on-vehicle will save time. Finally, consider the included accessories—tubing cutters, extra dies, and carry cases add value and convenience for ongoing brake line maintenance.
Tips for Accurate 3/16″ Flare Results
- Match the correct die size to your tubing outer diameter (OD).
- Clamp securely to prevent tube movement that could ruin the flare plane.
- Clean tubing ends and deburr edges before flaring to ensure a clean seal.
- Lubricate the die surfaces and tubing as recommended by the tool’s manufacturer.
- Inspect the flare for symmetry and take care to remove any burrs after completing the flare.
These options present a balance between portability, versatility, and durable construction. Depending on whether you work primarily on vehicles, prefer bench-mounted setups, or need a cost-effective compact tool for occasional use, any of these five picks can support reliable 3/16″ brake line flaring results.
