Mastercool 70058 Full AC Pipe Eccentric Tube Flaring Kit

Overview The Mastercool 70058-A Complete Kit includes everything you need to create consistent 45° SAE flares in copper and aluminum tubing. The precision flaring tool is packaged with a cutter, reamer, and rugged carrying case. Key Features Mastercool’s eccentric flaring cone rotates in a circular motion around the tubing edge, forming the flare gradually. This method reduces friction and tubing fatigue and ensures cleaner, more accurate flare walls — especially on softer copper. The 70033 heavy-duty cutter allows smooth, clean cuts on tubing from 1/8" to 1-1/8" (4–28mm) and features a large adjustment knob with a hardened blade. The 71685 inner-outer reamer preps the cut tubing by removing burrs on both the inside and outside edges, helping prevent sealing issues and improving flare performance. While some kits offer additional metric clamp bars, Mastercool designs each kit specifically for U.S. technicians, focusing on the most essential and job-relevant tools. This ensures every component serves a purpose and meets the standards of professionals in HVAC and automotive service.
