The tool-free push-to-connect design allows the fitting to be installed by simply cutting the pipe square and pushing the tubing into the fitting end until it seats at the internal stop. Rated to 250 PSI, the single-piece construction eliminates loose components during installation. This valve is sold in a 5-pack, making it practical for new construction rough-in work or multiple-fixture repair calls. Licensed plumbers and experienced pipe fitters are the primary installers for this type of stop valve.\u003c\/p\u003e\n\u003cp\u003eThe 3539-10 is suited for residential and light commercial plumbing installations where a compact inline shutoff is needed on 1\/2-inch supply lines. Its code-approved status covers behind-wall installations without access panels and direct in-ground burial applications, extending its use to concealed or underground service scenarios. It serves as a direct replacement for Qest and Flare It type fittings in retrofit and repair work, and is appropriate for new installations involving PEX, copper, or CPVC tubing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTool-free push-to-connect installation requires no special installation tools\u003c\/li\u003e\n  \u003cli\u003eRated to 250 PSI working pressure\u003c\/li\u003e\n  \u003cli\u003eSingle-piece design with no loose parts to assemble or misplace\u003c\/li\u003e\n  \u003cli\u003eApproved for behind-wall without access and direct in-ground burial installations\u003c\/li\u003e\n  \u003cli\u003eNSF-14 and NSF-61 certified; CSA\/ASTM and UPC listed and approved\u003c\/li\u003e\n  \u003cli\u003eCompatible with PEX, copper, and CPVC tubing on both ends\u003c\/li\u003e\n  \u003cli\u003eDisconnect by pulling back on the release ring to free the tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with PEX, copper, and CPVC tubing on 1\/2-inch supply lines.
