Thorstone 45° Single Flaring & Swaging Tool Kit for HVAC Tubing — Compact Case, Ratchet Wrench

The Thorstone 45° Single Flaring Tool & Swaging Kit is a complete professional set designed to make precise 45-degree single flares and swage connections on soft HVAC, refrigeration, and automotive tubing.

This compact kit combines a hardened flaring cone, two multi-hole flaring bars, a tube cutter, five swage adapters and a ratchet wrench in a blow-molded case so technicians, plumbers and DIYers can form reliable single flares and expand tubing without switching between multiple tools. It’s built for copper, brass, aluminum, magnesium and soft steel brake lines used in HVAC, refrigeration, plumbing and automotive brake work — not for hardened steel or cast iron.

How does the kit make a 45° single flare consistently?

The kit’s heat-treated steel cone and precision flaring bars create a controlled 45° flare by guiding the tubing and pressing evenly as the eccentric cone opens. The design reduces slippage and finishes the flare face smoothly for consistent seating against fittings.

• Heat-treated cone for steady, repeatable flaring pressure
• Eccentric cone action prevents tube drop and ensures even deformation
• Two flaring bars cover a wide range of outer diameters
• Automatic slight rebound and finishing rotation to smooth the flare face

Which tubing sizes and materials are compatible with this set?

This kit supports many common OEM and service tubing sizes and works with soft metals typical in HVAC, brake and refrigeration lines. It includes adapters and bar holes sized for small to medium OD tubing so you can handle most service jobs without extra purchases.

• Compatible ODs: 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 5/8", 3/4"
• Swage adapters for 3/16"–3/4" range (3-in-1 for 3/16", 1/4", 3/8")
• Materials: copper, brass, aluminum, magnesium, soft steel brake line
• Not for hardened steel, iron, or other heat-treated metals

What’s included and how does each part speed up the job?

The kit bundles the most-used parts to reduce trips to the toolbox and speed up on-site work. Each component has a clear role: cut, clamp, flare, swage and finish — all packed in a protective case for easy transport.

• Flaring cone — forms the 45° single flare with consistent angle
• Two flaring bars — multiple holes to clamp various ODs firmly
• Tube cutter — clean cuts from 1/8" to 1-1/8" (3–28 mm)
• Five swaging adapters — expand tube ends for snug fittings
• Ratchet wrench — speeds turning in tight spaces for repeatable results

How should I use and care for the tool to get long life?

Use steady, controlled pressure when flaring and allow the cone to rebound slightly to finish the flare face. Keep the tools clean, lightly lubricate moving parts and store them in the supplied blow-molded case to avoid nicks or corrosion.

• Clamp tubing squarely in the flaring bar before operating the cone
• Rotate cone slowly with consistent force to avoid wrinkling
• Clean metal shavings after cutting and lightly oil the cone threads
• Store components in the molded case to protect alignment and finish

Who is this for: The Thorstone 45° Single Flaring & Swaging Kit is aimed at HVAC and refrigeration technicians, automotive brake line specialists, plumbers and advanced home mechanics who need a reliable single-flare and swaging solution for soft metal tubing. If your work requires standard 45° single flares across common tubing sizes and you want a portable, all-in-one set, this kit covers most field and shop needs — but choose a double-flare tool if your application specifically requires double or bubble flares.
