Tube Flaring & Swaging Tools

Available64 products

Tube flaring and swaging tools widen the ends of tubing to make connections in plumbing, HVAC, and automotive applications. They apply pressure to reshape copper and other soft metal tubing while maintaining its strength since there's no loss of material. Flaring and swaging tools are commonly used on air, brake, and water lines.

Handheld Tube Flaring Tools

Handheld flaring tools are gripped with one hand while turning their flaring cone handle with the other hand. They have multiple slots that hold tubing of different sizes and clamp it in place as the flaring cone presses into the end of the tube. Flaring tools create a funnel-shaped end (flare) that forms a tight joint with a flared tube fitting, eliminating the need for brazing or soldering. The flare height is adjusted by moving the tubing up or down in the slot before flaring. Tube flaring tools are commonly used to connect refrigerant tubing in mini-split systems.

Flaring & Swaging Tool Kits

Flaring and swaging kits include a hand-operated tool with attachments to flare and swage tubing. Flaring creates a funnel-shaped end (flare) that forms a tight joint with a flared tube fitting, eliminating the need for brazing or soldering. Flares are commonly used to connect refrigerant tubing on mini-split line sets. Swaging enlarges the end of a tube so it slides over tubing of the same diameter to join two lengths without using fittings. The connection is then brazed to form a permanent joint.

Hammer-Driven Tube Flaring Tools

Hammer-driven flaring tools are struck on their shank to form flares more quickly but less precisely than hand-turn tools. These punch-style tools center their nose in tubing to create a 45° flare with uniform edges and a set height. Flaring tools create a funnel-shaped end (flare) that forms a tight joint with a flared tube fitting, eliminating the need for brazing or soldering. They are commonly used to connect refrigerant tubing in mini-split systems.

Hammer-Driven Tube Swaging Tools

Hammer-driven swaging tools are struck on their shank to thrust their tapered shaft into the end of tubing to widen it. These punch-style swagers enlarge the tube so it slides over another tube of the same diameter. The two lengths of tubing connect without using fittings, and the connection is then brazed to form a permanent joint.

Hammer-Driven Tube Swaging Tool Kits

Swaging kits include multiple punch-style tools to swage different tubing sizes. The tools are struck on their shank with a hammer to drive in their tapered shaft and widen the end of tubing. They enlarge the tube so it can slide onto another tube of the same diameter. The two lengths of tubing connect without using fittings, and the connection is then brazed to form a permanent joint.

Tube Expander Kits

These kits include an expander tool with multiple, interchangeable heads for different tubing diameters. The heads fit into the end of tubing and open out as the tool handles are squeezed, enlarging the tube so it can slide onto another tube of the same diameter. The two lengths of tubing connect without using fittings, and the connection is then brazed to form a permanent joint.
