It connects two sections of copper pipe without a center stop, allowing the fitting to slide fully onto the pipe — a common requirement when making repairs on existing lines without cutting out extra pipe length. Rated to 300 psi maximum working pressure and 250 degrees F maximum working temperature, this fitting is lead-free and certified to NSF-61\/372 and IAPMO PS117 standards. Licensed plumbers and pipefitters install this fitting on residential and light commercial piping systems.\u003c\/p\u003e\n\u003cp\u003eThis press coupling is suited for new construction and retrofit plumbing applications where copper pipe is used for domestic water supply, hydronic heating, or radiant systems. The push-to-connect press design eliminates open-flame soldering, making it well suited for installations in tight spaces, near combustibles, or in jurisdictions where torch work requires additional permits. The coupling without stop configuration is particularly useful in repair scenarios where minimal pipe removal is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo-stop design allows the fitting to slide fully over the pipe for repair and retrofit work\u003c\/li\u003e\n  \u003cli\u003ePress fitting connection — no soldering, flux, or open flame required\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eTemperature range: 0 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eLead-free copper construction, compliant with NSF-61\/372 and IAPMO PS117\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1.508 inches for standard 1-inch copper pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1-inch copper pipe in push-to-connect press fitting systems.

Shut off water supply and depressurize the line before cutting pipe or removing existing fittings. Follow IPC and local plumbing code requirements for press fitting use in potable water systems. Inspect the pipe end for burrs and deburr as needed before inserting into the fitting to ensure a proper press seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling without Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Press Fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.508 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F (-17 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: IAPMO PS117, NSF-61\/372\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MB12310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541425094962,"sku":"MB12310","price":23.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/509af04900a8577cea15aec75b5f7983.jpg?v=1785875747","url":"https:\/\/voomisupply.com\/products\/merit-brass-mb12310-copper-press-coupling-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
