The set is designed for use in a vise and includes a rotating 45° die head, split dies for five sizes, reaming cones and a cutter, all organized in a portable plastic case. Built from heat-treated steel and finished for corrosion resistance, the kit prioritizes repeatable precision so you can finish tight-sealing connections quickly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the DPTOOL kit create different flare types?\u003c\/h3\u003e\n\u003cp\u003eThe rotating die head and stepped reaming cones let you form single, bubble and double flares by following a sequence of operations.
