Thorstone 45° Double & Single Flaring Tool Kit — 5 Adapters, Heat-Treated Steel & Compact Case

Thorstone's 45° Double & Single Flaring Tool Kit is a complete, portable set for making precise 45-degree single and double flares in soft metal tubing used on brake, A/C and hydraulic lines.

This compact kit brings a full flaring solution to hobbyists, mechanics and mobile technicians who work on copper, brass, aluminum, magnesium and soft steel tubing. Thoughtfully organized in a blow-molded case, the set groups a hardened flaring yoke, a flaring cone, five size adapters and a tube cutter so you can prepare, clamp and flare tubes on-site or in the workshop. The components are built for repeated use and easier handling, with heat-treated steel in load-bearing parts and an alloy chrome swivel to reduce wear during forming.

What metals and tube sizes will this Thorstone kit handle?

The kit is engineered to shape soft metals commonly used in fluid lines, including copper, brass, aluminum and magnesium, plus softer steel tubing. It supports a wide range of diameters to cover automotive and HVAC needs.

• Adapters for 3/16", 1/4", 5/16", 3/8" and 1/2" tubing.
• Tube cutter fits 1/8" to 5/8" pipe diameters for clean preparation cuts.
• Not recommended for hardened or thick industrial steel and cast iron.

How does the kit form both single and double 45° flares?

The set includes a flaring cone and a flaring yoke (bar) designed to seat the tube and create controlled deformation. By selecting the appropriate adapter and using the cone against the tube end, you can produce either a single or a double flare at a consistent 45-degree angle.

• Flaring cone applies even pressure to form the angle cleanly.
• Flaring yoke secures the tube for repeatable, concentric flares.
• Adapters center different tube diameters to prevent slippage and distortion.

What durability and performance features should I expect from the components?

Key load-bearing pieces are heat-treated for strength and longevity, while the chrome-alloy swivel reduces friction during operation. The blow-molded case protects components and makes the kit quick to transport or store between jobs.

• Heat-treated steel yoke and flaring bar for long service life.
• Alloy steel chrome swivel reduces binding and wear.
• Compact blow-molded case keeps parts organized and protected.

How do I get consistent, leak-free joints using this kit?

Consistency starts with a square tube cut, correct adapter selection and steady pressure when forming the flare. The included cutter produces clean ends, and the adapters align the tube so the cone shapes an even 45° flare suitable for many fittings.

• Use the tube cutter to make a straight, burr-free cut before flaring.
• Choose the adapter that matches the tube OD for proper centering.
• Tighten the yoke evenly and apply steady force with the cone for uniform flares.

Who is this for? The Thorstone 45° Double & Single Flaring Tool Kit is aimed at DIY mechanics, mobile repair technicians, HVAC installers and home shop users who need a small, reliable flaring solution for brake lines, A/C lines and other soft-metal tubing tasks. It’s especially useful when portability, a range of common sizes and durable construction matter more than heavy industrial equipment. Thorstone backs the product with life-long support and 24/7 customer service for troubleshooting and replacement needs.
