It is a one-piece adapter used in potable water and hydronic plumbing systems where copper pipe meets PEX tubing. Licensed plumbers and PEX system installers use this fitting to make that transition cleanly and reliably. The adapter is part of the Sioux Chief Tomahawk PEX fitting line, which covers all major PEX connection systems and is backed by a 25-year warranty on fittings and tubing regardless of mixed or matched system connections.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial plumbing installations where a copper supply line or stub-out must connect to a PEX distribution run. Typical applications include new construction rough-in, remodel tie-ins at water heaters or shut-off valves, and retrofit work converting copper systems to PEX. The female sweat end accepts standard copper pipe for soldering, and the barb end secures PEX tubing with a crimp ring or clamp ring per the installer's preferred method.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece Tomahawk straight adapter construction for a reliable, low-profile transition\u003c\/li\u003e\n  \u003cli\u003e1-inch female sweat inlet accepts standard copper pipe for soldered connection\u003c\/li\u003e\n  \u003cli\u003e1-inch PEX barb outlet compatible with crimp-ring and clamp-ring installation methods\u003c\/li\u003e\n  \u003cli\u003eCovered by Sioux Chief 25-year warranty on fittings and tubing, mixed or matched systems\u003c\/li\u003e\n  \u003cli\u003ePart of the most complete PEX fitting and tubing offering in the plumbing trade\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 PEX plumbing systems requiring a 1-inch female sweat to 1-inch PEX barb transition.
