Thorstone 45° Flaring Tool Kit for Brake Tubing — Single & Double Flare, 5 Adapters, Cutter

Thorstone 45° Flaring Tool for Brake Line Tubing is a compact all-in-one kit that creates precise 45-degree single and double flares in soft metal brake and tubing lines.

This professional-style flaring set is built to shape copper, aluminum, brass and soft steel tubing commonly used in brake, HVAC and refrigeration systems. The kit combines a forged yoke, hardened flaring bar, five adapter sizes and a cutter inside a blow-molded case so you can prepare, clamp and form flares on-site or in a small workshop. It’s engineered to give repeatable flare geometry for secure fittings without bulky tooling.

How does the Thorstone set make accurate 45° flares?

The kit uses a hardened flaring cone and matching adapters to form 45-degree flare angles consistently. The flaring bar clamps the tube squarely while the cone is driven into the adapter mouth, producing a clean single or double flare depending on the procedure you follow.

• Forged yoke and heat-treated flaring bar for stable clamping pressure
• Chrome-alloy swivel to reduce friction during cone insertion
• Five adapter openings sized to match tube diameters and ensure correct flare geometry
• Includes a dedicated tube cutter for clean end preparation

What tubing sizes and materials work with this tool?

Thorstone’s kit supports common brake and service tubing sizes from 1/8" to 5/8" with adapter sizes for 3/16", 1/4", 5/16", 3/8" and 1/2". The tool is intended for soft metals such as copper, brass, aluminum and soft steel; it is not suitable for hard steels or cast iron.

• Adapters cover most automotive and HVAC tubing diameters
• Tube cutter fits 1/8"–5/8" pipe for clean cuts before flaring
• Use only on malleable metals for reliable flare formation
• Follow double- or single-flare procedures for application-specific needs

How portable and durable is the Thorstone flaring kit?

The set is organized in a blow-molded carrying case that keeps components secure and transportable. Components are made from heat-treated and forged steels with a chrome-alloy swivel, designed for workshop durability and repeated use when used as intended.

• Blow-molded case for tidy storage and site transport
• Heat-treated flaring bar resists deformation under clamp pressure
• Forged yoke stands up to repeated tightenings without binding
• Compact footprint fits small toolboxes and vehicular trunks

What’s included and how does it support different jobs?

This kit bundles the essential pieces needed to cut, clamp and form single or 45° double flares without purchasing extra accessories. The range of adapters and an integrated cutter make the set flexible for automotive brake lines, HVAC lines and other fluid tubing tasks where flared fittings are used.

• Flaring cone for forming 45° flares
• Flaring bar (yoke) and forged clamping assembly
• Tube cutter suitable for 1/8"–5/8" tubing
• Five adapter sizes covering 3/16"–1/2" tubing ranges
• Blow-molded case for organization and protection

Who is this for: The Thorstone 45° Flaring Tool is aimed at home mechanics, HVAC technicians, refrigeration hobbyists and small-shop professionals who need a portable, reliable kit for making consistent 45-degree single or double flares in soft tubing. If you work with brake lines, A/C lines or similar malleable metal tubing and require repeatable flare geometry without industrial machinery, this set offers the necessary sizes and components for most common repair and installation jobs.
