Flaring Tools: Professional Selection and Usage Guide 2026

What Are Flaring Tools and What Are They Used For?

Flaring tools are indispensable hand tools in the HVAC and refrigeration sector, used to expand the end of copper and aluminum tubes into a cone (usually at a 45° angle) to create a leak-tight flare nut connection. Flare connections are made at every point where copper tube is used, from split air conditioner installation to commercial refrigeration cabinets, and from heat pumps to industrial chiller lines. A proper flare reduces the probability of refrigerant leaks to almost zero, while a skewed, cracked or incompletely angled flare quickly reduces system performance and causes refrigerants such as R32, R410A and R290 to leak into the environment.

For this reason, for a professional HVAC technician, choosing the right flaring tool is not just a matter of tool preference; it is also a critical decision directly related to occupational safety, warranty conditions and customer satisfaction. At Yedepa.com, in this category we take care to stock only field-tested products from reliable brands of European and Asian origin.

Technical Details and Working Principle of Flaring

Flaring the end of a copper tube is a more delicate process than it appears. For a correct flare connection, the following steps should be applied in order:

Tube cutting: The tube must be cut square with a right-angle tube cutter, never with a hacksaw. Otherwise the flare mouth will be asymmetrical.
Deburring: If metal burrs raised on the inner wall mix with the refrigerant inside, they wear out the compressor. A reamer-type deburring tool must always be used before flaring.
Fitting the flare nut: The flare nut must be slipped onto the tube first; otherwise it will not pass over the tube once the flare is made.
Flaring bar positioning: The tube should be clamped so that it protrudes above the block flaring bar by the amount specified in the size table (usually 1-1.5 mm).
Flaring: The eccentric or conical cone expands the tube at a 45° angle with a certain torque. The result should be a shiny, crack-free and symmetrical cone.

In conventional flaring sets this process is done by turning the ratchet handle by hand; modern cordless flaring machines, on the other hand, make every flare to the same standard thanks to a torque-controlled motor. Especially for an HVAC service vehicle making 20-30 flares a day, this difference is revolutionary in terms of both time and work quality.

Flaring Tool Types and Models

The flaring tools you will come across on the market can be examined in four main groups:

Classic conical (yoke-type) flaring tools: The oldest design, in which a screw handle pushes the cone into the tube mouth. Cheap, but requires experience for the correct torque.
Eccentric (cam-type) flaring tools: The cone head rotates eccentrically, expanding the tube step by step. The risk of a skewed flare is quite low, and it is the sector standard today. ST-519FT, ST-806FT-L, DSZH WK-806FT-L and WK-806A are popular models of this type.
Ratcheting flaring tools: The eccentric head is turned with a ratchet handle, making it easy to use even in tight spaces. The Value VFT-809-I and CH-WK806N-L are popular choices in this category.
Cordless flaring machines: They run on an 18V or 21V Li-ion battery, and a torque sensor controls the angle with millimetric precision. For fast, standardized and fatigue-free flaring, the Super Stars ST-E900A, ST-E809AM-L and Value VET-19C-F are the leading products.

Which Model to Choose? Decision Guide

The criteria to consider when choosing the right flaring tool can be summarized in three scenarios according to your daily workload:

User Profile	Recommended Type	Example Model
Technician doing a few air conditioner installations a week	Eccentric manual	DSZH WK-806A, ST-806FT-L
Technician doing multiple jobs daily from a service vehicle	Ratcheting eccentric	Value VFT-809-I, CH-WK806N-L
Intensive commercial refrigeration / VRF projects	Cordless automatic	ST-E900A, ST-E809AM-L, Value VET-19C-F
Job site requiring a European-standard warranty	Premium eccentric	Rothenberger Roflare Revolver

When making the investment decision, you should also consider compatibility with the tube cutter, deburring tool and vacuum pump you have. For cordless models, battery capacity (for example, the ST-E900A's 2200 mAh battery can make about 100 flares on a full charge) and the availability of spare batteries will be decisive.

Professional Selection Criteria

Looking only at the price tag when buying a flaring tool is a big mistake. Be sure to evaluate the following criteria:

Flaring bar material: Aluminum flaring bars are light but deform over time; hardened steel flaring bars (Rothenberger, DSZH WK-806A) produce identical flares for years.
Tube diameter range: The sizes most frequently encountered in Turkey are 1/4", 3/8", 1/2", 5/8" and 3/4". Make sure the set fully covers these five sizes.
Inch + metric compatibility: Some sets contain only inch flaring bars, others only metric. 2-in-1 models such as the ST-E809AM-L are ideal for technicians working in both sizes.
Cone head angle: The SAE J513 standard is 45°. In Turkey 45° is also used on standard split air conditioners; make sure the set is at this angle.
Eccentric design: If you stay away from the yoke type and prefer eccentric or ratcheting models, your flares will come out much more symmetrical.
Torque control: In cordless models, the torque sensor allows even an inexperienced technician to make professional flares.
Brand service network: Super Stars, Value, DSZH and Rothenberger are brands with spare parts support in Turkey.

Brand Comparison: Super Stars, Rothenberger, Value, Hengsen, DSZH Tools

Super Stars is one of the brands most preferred by the HVAC service sector in Turkey thanks to its price-performance balance and wide range of models. Its cordless models such as the ST-E900A and ST-E809AM-L have redefined the sector's automatic flaring standard.

Rothenberger, a German-origin giant in installation tools, is the leader of the premium segment. The Roflare Revolver flaring tool serves for decades with its revolving cone technology and hardened steel body.

Hengsen, meanwhile, offers innovative solutions with innovative ratcheting + drill-compatible models such as the CH-WK806N-L, especially for technicians looking to save space in service vehicles.

Use and Maintenance Recommendations

To get the most out of your flaring tool, we recommend paying attention to the following use and maintenance rules:

Clean the flaring bar surface before each flare. Old flare burrs leave marks on the new tube.
Lightly lubricate the cone head. A drop of refrigeration oil (POE or mineral) reduces cone-copper friction, protecting both the tool and the tube.
Tighten the flaring bar screws evenly. If you press too hard on one side, the flare will come out elliptical.
Do not let the copper tube protrude too far. 1 mm of excess protrusion means a cracked flare; too little protrusion means a shallow flare.
Battery life in cordless models: Do not run the charge down completely before recharging; keep it in the 20%-80% range. The 2200 mAh capacity of the ST-E900A battery provides 500+ full cycles when this rule is followed.
Put it back in its clean case after use. Moisture and transport knocks damage the eccentric mechanism over time.
Annual check: Measure the parallelism of the flaring bar with a caliper once a year; if there is deformation, it is economical to buy a new one.

Frequently Asked Questions (FAQ)

1. Does a cordless flaring machine really make better-quality flares than a manual set?
Yes. Thanks to their torque sensor, cordless models make every flare at the same angle and pressure, reducing human error to almost zero. The ST-E900A and ST-E809AM-L are the leading models in this segment.

2. What is the difference between an eccentric flare and a classic conical flare?
In the classic conical (yoke) design, the cone applies pressure to the tube at a single point and the risk of a skewed flare is high. In the eccentric design, the cone rotates and expands every side of the tube equally; this produces a symmetrical, leak-tight flare.

3. On which tube diameters can I make flares?
Standard sets support the 1/4", 3/8", 1/2", 5/8" and 3/4" inch sizes or their metric equivalents of 6, 8, 10, 12, 16, 19 mm. 2-in-1 models such as the ST-E809AM-L work in both systems.

4. Is a special flare required for R32 and R410A refrigerant lines?
No, a 45° SAE standard flare is sufficient for both refrigerants. However, since R410A operates at high pressure, it is essential that the flare quality is flawless; this is the reason to invest in a quality eccentric or cordless set.

5. Is the Rothenberger Roflare Revolver worth being this expensive?
Yes, if you make 15+ flares a day and work on projects where a warranty is mandatory. The hardened steel flaring bar of the Roflare Revolver keeps its parallelism for years; in the long run it more than pays for itself.

6. Are a tube cutter and deburring tool needed along with the flaring tool?
Absolutely. Sets such as the DSZH WK-806FT-L include a tube cutter and deburring tool in the package; this way you avoid the cost of additional accessories.

7. Is the flaring tool I buy from Yedepa.com under warranty?
Yes. All products are shipped with a distributor/manufacturer warranty; for technical support you can reach our customer service in Turkish.
