Professional Hydraulic Tube Flaring Kit

Deliver professional-grade flares on brake, fuel, transmission, and hydraulic lines without the guesswork. At its heart is a heavy-duty hydraulic ram that generates up to 10 tons of force, so you can form perfect SAE-compliant inverted and bubble flares in seconds. The universal head accepts five die sizes (3/16″, ¼″, 5/16″, 3/8″ and ½″) plus the included GM transmission-cooling adapters, so it handles everything from copper-nickel brake tubing to OEM-steel lines. You’ll also get a quick-release cutter, a deburring reamer, a T-handle for manual flaring, and a rugged carry case to keep every piece organized. Built from hardened alloy steel and backed by our lifetime warranty, this kit is engineered to stand up to daily shop use and weekend-wrenching alike.

Head-to-Head vs. Mastercool 72485
While the Mastercool 72485 focuses primarily on transmission-cooling lines (3/8″ & ½″) and delivers inverted flares only, the 4Lifetime set goes further:

Broader Tube Compatibility: Ours works on steel, copper, aluminum, and CuNi lines in five sizes; theirs is limited to 3/8″ & ½″ steel.

Flare Types: The 4Lifetime kit effortlessly creates inverted, double, and 37° bubble flares—all in one head—whereas the Mastercool tool handles only inverted flares.

Hydraulic Pump Performance: A pre-charged 3,000 psi pump gives our ram faster cycle times and more consistent flare quality; the Mastercool unit relies on a manual piston.

Warranty & Support: 4Lifetime stands behind every tool with a lifetime warranty and responsive customer service; Mastercool’s coverage is more limited.

When you need one tool to tackle every tubing job—bends, cuts, deburrs, and flares—the 4Lifetime Universal Hydraulic Tube Flaring Set outclasses the competition in versatility, durability, and ease of use.
