It accepts 1 inch copper tube and fits 3\/4 inch pipe, making it a practical choice for repairs and new installations where a flame-free connection method is preferred. Rated at 125 psi WOG (water, oil, gas), it handles typical domestic and light commercial service pressures. The brass body withstands working temperatures up to 180 degrees F. Licensed plumbers and experienced pipefitters install this fitting in water supply, heating, and light commercial fluid systems.\u003c\/p\u003e\u003cp\u003eThis compression coupling is suited for residential and light commercial plumbing applications where a reliable, tool-only joint is required. Common install scenarios include in-wall or under-slab repairs where soldering is impractical, as well as above-grade water supply piping. It is appropriate for water supply lines, hydronic heating distribution, and similar low-to-medium pressure fluid service within its rated temperature and pressure limits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction resists corrosion in water and fluid service\u003c\/li\u003e\n\u003cli\u003e125 psi WOG pressure rating suits standard residential and light commercial supply lines\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature of 180 degrees F compatible with hot water service\u003c\/li\u003e\n\u003cli\u003eCompression-style connection requires no solder, flame, or threading\u003c\/li\u003e\n\u003cli\u003eFits 1 inch copper tube with 3\/4 inch pipe sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression fitting for 1 inch copper tube in standard residential and light commercial plumbing systems operating within 125 psi WOG and 180 degrees F temperature limits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply line before disassembling any existing piping or fitting the coupling. Ensure tube ends are cut square and deburred before seating the compression ring to achieve a leak-free joint. Do not overtighten the compression nut, as excess force can deform the ferrule and compromise the seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper Tube Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating (WOG)\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LEGEND VALVE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 303-125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51541068120370,"sku":"303-125","price":37.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a48a929468183ee28e1b2e5acebc9f63.jpg?v=1785868082","url":"https:\/\/voomisupply.com\/products\/legend-valve-303-125-brass-compression-pipe-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
