Part of the Tomahawk PEX fitting line, it gives licensed plumbers a reliable transition point between PEX distribution lines and copper sweat connections in residential and light commercial plumbing systems. The adapter is a single-piece construction, keeping the connection count low and the installation straightforward. It is rated for use across Sioux Chief PEX systems and carries a 25-year warranty on both fittings and tubing regardless of whether components are mixed or matched within the Sioux Chief lineup.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for new construction rough-in and retrofit applications where a PEX supply line terminates at a copper sweat connection. Typical scenarios include connecting PEX branch lines to copper stub-outs at fixtures, valves, or manifold transitions. The 1-inch size makes it appropriate for main distribution runs in residential systems or branch feeds in light commercial plumbing where larger flow capacity is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece straight adapter construction minimizes potential leak points\u003c\/li\u003e\n  \u003cli\u003e1-inch PEX inlet to 1-inch male sweat outlet transition\u003c\/li\u003e\n  \u003cli\u003ePart of the Tomahawk PEX fitting series from Sioux Chief\u003c\/li\u003e\n  \u003cli\u003e25-year warranty covering fittings and tubing, mixed or matched within the Sioux Chief PEX system\u003c\/li\u003e\n  \u003cli\u003eCompatible across all major Sioux Chief PEX systems without warranty restrictions based on mixed connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Sioux Chief PEX tubing and fitting systems.
