Double flaring tools are essential for creating reliable and leak-free brake and fuel lines. But with so many options available, how do you choose the right on-car double flaring tool for your needs? This guide will explore various types of flaring tools, their pros and cons, and popular recommendations from experienced mechanics.
Types of Double Flaring Tools
There are three main types of double flaring tools:
- Bar-Type Flaring Tools: These are the most common and affordable type. They use a clamping bar and a cone-shaped flaring tool to create the double flare. While portable and suitable for occasional use, they can be challenging to use on harder lines and may require more effort to achieve a perfect flare. Some users recommend tightening the wing nuts with the bar for a better grip.
- Screw-Type/Yoke-Type Flaring Tools: These tools use a screw mechanism to apply pressure and form the flare. They often provide more precise and consistent results compared to bar-type tools. Examples include the Cal-Van and ADT tools, which are praised for their ease of use and ability to flare even steel hard lines with proper preparation (heat and lubrication).
- Hydraulic Flaring Tools: These tools use hydraulic pressure to create the flare, making the process significantly easier and faster, especially on tougher materials. They are often preferred for professional use due to their speed and efficiency. The Mastercool hydraulic flaring tool is a popular choice among mechanics, despite its higher price point. While praised for its speed, some users note that the flare might be slightly off-center occasionally.
Popular On-Car Double Flaring Tool Recommendations
Several brands and models are frequently recommended by users:
- Mastercool Hydraulic Flaring Tool: Considered the top choice for a long-lasting, high-quality tool, the Mastercool is praised for its ease of use and ability to tackle even challenging flaring tasks. While expensive, many users believe it’s a worthwhile investment for frequent use. The 72475 model is the current version, replacing the older 71475.
- Eastwood Flaring Tool: This bench-mounted tool is highly regarded for its precision and consistent results. Users report achieving perfect flares every time, even on stainless steel lines. The main drawback is its bench-mounted design, requiring lines to be removed from the vehicle.
- Rigid Flaring Tool: Available at Home Depot and online retailers, the Rigid flaring tool offers a balance of affordability and performance. It’s praised for its accuracy, although it can be slower to use than hydraulic options.
- Cal-Van Flaring Tool: This screw-type tool is lauded for its ease of use and ability to create excellent flares, even for beginners. Its affordability makes it a popular choice for occasional use.
- Blue-Point Flaring Tool: Described as a durable and reliable option, the Blue-Point flaring tool is similar in design to cheaper alternatives but built to a higher quality standard.
Tips for Achieving Perfect Flares
Regardless of the tool you choose, proper preparation is crucial for successful flaring:
- Square Cut: Ensure the tubing is cut perfectly square.
- Chamfer Edges: Chamfer both the inside and outside edges of the tube to prevent cracking and ensure a smooth flaring process. Specialized chamfering tools are available to simplify this process.
- Lubrication: Use a suitable lubricant to reduce friction and prevent damage to the tubing and the flaring tool.
Conclusion
Selecting the right on-car double flaring tool depends on your budget, frequency of use, and required precision. While hydraulic tools offer speed and ease of use, manual options like the Eastwood or Cal-Van provide excellent accuracy for a lower cost. Always prioritize proper tube preparation for consistent, leak-free flares. By understanding the different types available and considering your specific needs, you can choose the best double flaring tool for your automotive projects.
