Wostore Eccentric Flaring Kit — 7-die 3/16–3/4" 45° heavy-duty kit with hardened eccentric cone

Wostore Eccentric Flaring Kit is a heavy-duty 7-die tool set that makes precise 45° flares in copper, brass, aluminum and mild steel tubing for HVAC, refrigeration, gas and brake-line work.

This compact kit brings a hardened, eccentrically-mounted flaring cone, seven die sizes and a built-in tube cutter in a portable case so technicians and DIYers can form reliable, uniform flares on-site. Built from 45# steel parts with a large feed-screw handle and single clamp screw, the set focuses on durable mechanics and easy operation to reduce galling and produce consistent flare walls.

How does the eccentric flaring cone improve flare quality?

The eccentric design advances metal flow during the forming process so the tubing rolls outward evenly instead of tearing or bunching. That rolling action helps produce uniform, smooth flare walls and a tighter joint without excessive deformation of the tube end.

• Hardened steel eccentric cone for even metal distribution
• 45° flares suited for common HVAC and refrigeration fittings
• Designed to minimize galling and wall thinning
• Works on soft copper, brass, aluminum and mild steel tubing

Which tube sizes and materials are compatible with this kit?

The kit includes seven dies sized 3/16", 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4" to cover standard HVAC and refrigeration lines. The cutter accommodates tubing from about 1/8" up to roughly 1 3/16" (4–30 cm), making it versatile for multiple trades.

• Dies for 3/16" through 3/4" tubing
• Tube cutter range ~1/8"–1 3/16" (4–30 cm)
• Suitable for copper, brass, aluminum, mild steel
• Commonly used in gas, water, refrigeration, HVAC and brake lines

How easy is it to use and transport on a jobsite?

A single clamp screw and a large feed-screw handle simplify clamping and turning, reducing fatigue and speeding repetitive work. When the job is done, each component snaps into a hard plastic case with a carry handle so tools stay organized and ready to move between vehicles or sites.

• Single clamp screw for quick tube setup and release
• Large handle for smooth feed-screw operation and low effort
• Blow-molded plastic case for secure storage and portability
• Compact footprint for service van or toolbox shelf

What maintenance or care does the tool require?

Basic upkeep keeps performance consistent: wipe metal parts after use, lightly oil the feed screw and cone, and store dies in the case to prevent corrosion and dings. Inspect dies regularly for burrs and replace if worn to maintain clean flares.

• Clean metal particles and apply light lubrication to moving parts
• Keep dies and cone free of nicks or burrs
• Store in the supplied case to protect alignment and finish
• Periodic inspection prevents poor flares and premature wear

Who is this for: The Wostore Eccentric Flaring Kit is intended for HVAC and refrigeration technicians, plumbers, automotive brake-line specialists and capable DIYers who need a rugged, portable solution for producing consistent 45° flares across common tubing sizes. If you require a durable, easy-to-use flaring toolset that handles a range of metal tubing and fits neatly in a service kit or van, this set is built for that workflow.
