It is a single-piece fitting with no loose parts to assemble or misplace, which reduces the chance of installation errors. Rated to 250 psi, this adapter is built for reliable performance in pressurized water supply systems. It carries NSF-14, NSF-61, CSA\/ASTM, and UPC certifications, making it code-approved for concealed behind-wall installations and direct in-ground burial without requiring an access panel. Plumbers and pipefitters working on residential and light commercial water distribution systems are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for use in potable water supply lines where a CTS-to-MPT transition is needed. Its code-approved status for behind-wall and direct burial applications makes it particularly useful in new construction roughing and remodel work where access after installation is limited or not practical. Each package contains 5 pieces, making it convenient for jobs requiring multiple connections. The fitting is listed as a replacement for Qest and Flare It type fittings, allowing techs to swap out legacy connections without reworking the surrounding pipe layout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-piece quick connect design — no separate parts to assemble or lose on the job\u003c\/li\u003e\n\u003cli\u003eRated to 250 psi for reliable service in pressurized potable water systems\u003c\/li\u003e\n\u003cli\u003eCode-approved for behind-wall without access and direct in-ground burial installations\u003c\/li\u003e\n\u003cli\u003eNSF-14 and NSF-61 certified for use in potable water applications\u003c\/li\u003e\n\u003cli\u003eCSA\/ASTM and UPC listed and approved\u003c\/li\u003e\n\u003cli\u003eCompatible replacement for Qest and Flare It type fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eListed as a direct replacement for Qest and Flare It type fittings.
