Mastercool 70057-A Eccentric Flaring Tool – 45° SAE Flares for 1/4" to 3/4" Tubing – Automatic Torque Release – Standard Range – HVAC and Automotive

OverviewThe Mastercool 70057-A delivers precise 45° SAE flares using an advanced eccentric cone mechanism that minimizes stress on the tube while ensuring a smooth, accurate flare. It’s built to handle routine HVAC and automotive flaring jobs with confidence.Key FeaturesUnlike conventional flaring tools that press the cone directly into the tubing, Mastercool’s eccentric design rotates the cone in a circular motion. This reduces friction, distributes pressure more evenly, and prevents cracking or deforming softer tubing. It creates consistent, professional-grade flares every time.The tool supports 1/4", 5/16", 3/8", 1/2", 5/8", and 3/4" O.D. tubing sizes and is ideal for technicians working on A/C systems, refrigeration lines, and brake or fuel tubing. Its forged steel yoke and rail-guided design provide accuracy, while the torque-release clutch ensures consistent flare depth and finish.Why MastercoolMastercool is a U.S.-based company with nearly half a century of experience delivering precision tools to HVAC and automotive professionals. Our tools are trusted worldwide and backed by reliable, U.S.-based customer support.
