Fanmoss Brake Line Flaring Tool Kit — bench-mounted 3/16"-3/8" double & bubble flare, stainless steel

Fanmoss Brake Line Flaring Tool Kit is a stainless-steel bench-mounted kit that makes precise 45° single, double, and bubble flares on 3/16"–3/8" tubing for brake, fuel, and transmission cooler lines.

This compact kit gathers the cones, dies, clamp, and T-handle screw needed to produce consistent, leak-resistant flares in soft metals and common steels. Designed for use with a bench or hitch vise (not under-car vise application), the toolset speeds repairs and reduces trial-and-error, giving technicians and DIYers reliable flare geometry every time.

How does this kit create different types of flares?

The Fanmoss kit uses interchangeable cones and die blocks to form single 45° flares, double (inverted) flares and bubble-style flares. Change the cone and the die position, clamp the tube, and advance the T-handle screw to shape the metal uniformly without deforming the tubing ID.

• Includes cones for single and double flare profiles and a bubble flare option
• Die blocks accept 3/16", 1/4", 5/16", and 3/8" tubing sizes
• 6" T-handle screw supplies steady, controlled pressure
• Vise-mounted clamp holds the die and tube square for repeatable results

What materials and tube sizes are compatible with this flaring tool?

This kit works with soft metals and common automotive tubing: copper, aluminum, 304 stainless, and mild steel. Its die set covers the most frequently used diameters for brake and fuel systems so you can repair or fabricate lines without constant tool changes.

• Fits 3/16", 1/4", 5/16", and 3/8" tubing diameters
• Suitable for copper, aluminum, 304 stainless, and steel tubes
• Not recommended for oversized, hardened, or exotic alloys beyond listed types
• Best results with properly deburred and clean tube ends

How should I use and maintain the Fanmoss flaring tool for best results?

Preparation and lubrication are the keys: deburr the tube inside and out, apply a light anti-seize to the cut end, and oil the flaring cones for smooth forming. Secure the die assembly in a bench or hitch vise, tighten the clamp, then advance the T-handle evenly to avoid uneven flares.

• Deburr both inside and outside of the tube before flaring
• Apply light anti-seize to tube ends and oil on cones for smoother operation
• Use a bench or hitch-mounted vise to anchor the clamp (not under-car use)
• Inspect finished flares for uniformity and proper seating before assembly

Will this kit hold up for shop or occasional home use?

Yes—the components are heat treated and oxidation-finished stainless steel built for frequent cycles and resistance to wear. The robust construction and tested design deliver consistent 45° flares, helping professionals save time and hobbyists avoid rework.

• Stainless-steel parts with heat treatment for hardness and longevity
• Oxidation finish resists corrosion and surface damage
• Designed and tested to provide stable, repeatable flaring performance
• Compact footprint for bench or mobile service setups

Who is this for: The Fanmoss Brake Line Flaring Tool Kit is built for professional mechanics, restoration enthusiasts, and DIYers who work on brake, fuel, or transmission cooler lines and need reliable, repeatable flares across common tube sizes. If you frequently make or repair flared connections and want a durable, vise-mounted kit with double and bubble flare capability, this set covers the essential sizes and operations without pro shop complexity.
