Forged from high-carbon steel with an ergonomic fixed handle and strong return spring, the tool gives controlled leverage and reduced hand fatigue. The kit covers a range of common refrigeration and air-conditioning tube sizes so you can match fittings and create snug, leak-minimizing joins.\u003c\/p\u003e\n\n\u003ch3\u003eHow precise are the expansion sizes and what sizes are included?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit provides a selection of heads sized to deliver predictable, repeatable expansions across common tubing diameters.
