Part of the Tomahawk PEX fitting line, this adapter allows plumbers to transition between PEX distribution lines and copper sweat connections in residential and light commercial water supply systems. The single-piece construction supports a clean, reliable joint with no additional coupling required. SIOUX CHIEF backs all Tomahawk fittings and tubing with a 25-year warranty regardless of whether tube and fittings are mixed across system types.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for potable water supply installations where PEX tubing terminates at a copper sweat connection point, such as at shutoff valves, manifolds, or fixture supply stubs. It is a common solution in new construction and retrofit plumbing where installers are transitioning from a PEX run to an existing or new copper sweat assembly. Licensed plumbers and experienced plumbing contractors are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece straight adapter — no extra coupling needed at the transition point\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch PEX inlet to 3\/4-inch male sweat outlet configuration\u003c\/li\u003e\n  \u003cli\u003ePart of the Tomahawk PEX fitting system, compatible with all major PEX connection methods\u003c\/li\u003e\n  \u003cli\u003e25-year warranty covering fittings and tubing, mixed or matched across system types\u003c\/li\u003e\n  \u003cli\u003eDesigned for potable water supply applications in residential and light commercial settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for use with 3\/4-inch PEX tubing systems transitioning to 3\/4-inch male copper sweat connections.
