Uniweld's UDFT Deluxe Flaring Tool is specifically designed to meet R-410A flaring specifications and all 45° flares for tubing, 1/8"-3/4" O.D. Tubing. The internal break away clutch that disengages when flare is completed prevents over flaring and crushing the copper tubing. The 3/4″-12 point reversible ratchet wrench included reduces the amount of effort required to manually flare in a confined work space. The 3/8″ square drive can be used with a cordless electric drill for faster flaring. Features an eccentric off center cone that spins on an axis and rolls out a perfectly uniform 45° flare with a burnished flare surface. Mini Split A/C units are becoming increasingly popular and require flare connections on each end of the copper line set to connect the evaporator and condenser. Since R-410A is a much higher-pressure refrigerant, Mini Split manufacturers established R-410A flaring specifications that require a larger diameter, deeper flare for more surface area to seal against the male flare fitting and produce a stronger connection. Uniweld's Deluxe Flaring Tool features a built-in tube stop height gauge that makes a perfect R-410A flare without the guess work. Specifically designed to meet R-410A flaring specifications and can also be used on all 45° flares for Soft Copper, Brass and Aluminum Tubing.
