Constructed from copper, this one-piece adapter is sized for 3\/4-inch nominal connections. It follows the F1807 standard crimp end on the PEX side, making it compatible with standard PEX crimp rings and tools. Plumbers use this fitting when transitioning between PEX supply lines and existing CPVC distribution piping in residential and light commercial systems. The 25-year warranty covers both fittings and tubing regardless of mixed or matched system connections.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for potable water distribution systems where a contractor needs to transition from flexible PEX tubing to rigid CPVC pipe. Typical install scenarios include new construction rough-in, remodel work tying into existing CPVC runs, and repair situations where a PEX supply line terminates at a CPVC branch or riser. The fitting is part of the Sioux Chief Tomahawk PEX fitting line, which covers all major PEX connection systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions F1807 PowerPEX crimp connections to CPVC pipe in one fitting\u003c\/li\u003e\n\u003cli\u003eCopper construction for durability in potable water applications\u003c\/li\u003e\n\u003cli\u003e3\/4-inch nominal size fits standard residential supply line sizing\u003c\/li\u003e\n\u003cli\u003eOne-piece design with no separate insert required\u003c\/li\u003e\n\u003cli\u003eCovered by a 25-year warranty on fittings and tubing, mixed or matched systems included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style transition fitting for 3\/4-inch F1807 PowerPEX crimp systems connecting to 3\/4-inch CPVC pipe in residential and light commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber.
