Tubing Tools

Tubing tools cut, bend, flare, swage, and deburr soft metal tubing, copper, aluminum, brass, and sometimes steel, to create leak-resistant connections in HVAC, refrigeration, plumbing, and automotive fluid line work. We stock tube cutters, benders, flaring and swaging tools, deburring tools, and complete kits sized for the tubing diameters and materials you work with most. Getting the cut, bend, or flare wrong produces a joint that leaks, restricts flow, or fails under pressure.

A tube cutter produces a clean, square cut so the tube seats against a fitting or flare die, while a hacksaw leaves burrs that restrict flow and weaken the joint. Flaring tools form a 45-degree cone at the tube end, single flares for lower-pressure fuel and cooling lines, double flares for brake lines that need higher pressure resistance. A quality bender uses formed guides to curve tubing without kinking or flattening it, since a kink restricts flow and weakens tube.

How Tubing Tools Work

A tube cutter uses a rotary wheel that scores and cuts through the tube wall as it rotates around the tubing, producing a square edge. Benders use formed guides or mandrels that support the tube wall from the inside or outside as it curves, preventing the wall from collapsing. Flaring tools clamp the tube and press a cone-shaped die into the end to form the flare shape, while swaging tools expand one tube end so it can accept another tube of the same diameter without a separate fitting.

Types of Tubing Tools

Tube cutters use a rotary wheel to produce clean, square, burr-minimal cuts, essential prep work before flaring or brazing a joint. Tubing benders use formed guides or mandrels to curve tubing to a specific angle without kinking or flattening the wall, available in lever, ratchet, and hydraulic styles for different tubing sizes and materials. Flaring tools form a cone at the tube end for flare fittings, with single-flare tools suited to lower-pressure fuel and cooling lines and double-flare tools required for brake lines and other high-pressure applications. Deburring and swaging tools finish the job, removing sharp edges left by cutting and expanding tube ends to accept another tube without a separate coupling.

Common Applications

• HVAC and refrigeration line installation and service
• Plumbing work with copper and soft metal tubing
• Automotive brake, fuel, and transmission cooling line repair
• General fabrication with copper, aluminum, and steel tubing

Choosing the Right Tubing Tools

Match tool capacity to the tubing diameters and materials you work with most, since most cutters and benders are rated for a specific size and material range. If you work on brake lines, make sure your flaring tool supports double flares, not just single. A complete kit covering cutting, bending, flaring, and deburring in one case saves time over sourcing tools individually. Every tool we carry is backed by manufacturer warranty support, and our team can help match tool capacity to your typical tubing sizes and materials.

Frequently Asked Questions

What’s the difference between a single flare and a double flare?

A single flare forms one layer of metal at a 45-degree angle, suited to lower-pressure fuel and cooling lines, while a double flare folds the metal over for a stronger joint required on brake lines and other high-pressure applications.

Why use a tube cutter instead of a hacksaw?

A tube cutter produces a clean, square, low-burr cut that seats properly against a fitting or flare die, while a hacksaw tends to leave burrs and an uneven edge that weaken the finished joint.

What materials can tubing benders handle?

Most benders handle soft metals like copper and aluminum, while professional-grade hydraulic and heavier-duty benders can also handle harder materials like steel, so check the tool’s rated material and diameter range before use.

What is a swaging tool used for?

A swaging tool expands one end of a tube so a second tube of the same diameter can be inserted directly into it, creating a joint without a separate coupling fitting.
