Mastercool 70059 Eccentric Flaring Tool – Extended Range 45° SAE Flares for 1/4" to 7/8" Tubing – Impact Compatible – Forged Steel Yoke – HVAC/R Applications

OverviewThe Mastercool 70059 is the only eccentric flaring tool on the market that supports flaring up to 7/8" O.D. tubing. Built for HVAC and refrigeration pros, it combines heavy-duty forged construction with a rail-guided yoke and 3/8" drive compatibility.Key FeaturesUnlike traditional flare tools that push the cone straight into the tubing, Mastercool’s eccentric mechanism rotates the cone in a circular motion. This gradual forming process reduces metal fatigue, improves flare wall uniformity, and ensures a clean, leak-free seal every time. The forged chrome-plated yoke and rail-guided design keep the cone and clamp bar perfectly aligned during use.The 70059 supports 1/4" to 7/8" tubing and can be operated manually or with a 3/8" impact wrench for speed and convenience. It’s engineered for serious professionals working on high-capacity HVAC and refrigeration systems.Why MastercoolBacked by nearly 50 years of experience, Mastercool is a trusted U.S. manufacturer known for building rugged, reliable tools for professionals.
