It joins two sections of copper pipe without soldering, making it well suited for repair and retrofit work where open-flame tools are restricted or impractical. The fitting is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 250 degrees F, covering the full range of domestic hot and cold water service. The outside diameter measures 1.252 inches. Lead-free construction meets drinking water contact requirements under NSF-61\/372. Licensed plumbers are the primary installers, though the push-to-connect design is also used by mechanical contractors on commercial hydronic systems.\u003c\/p\u003e\u003cp\u003eThis union fitting is appropriate for residential and light commercial plumbing applications including potable water supply lines, hydronic heating distribution, and in-wall or under-slab copper pipe repairs where torch use is not permitted. The press-style end connection simplifies union service: the pipe sections can be disconnected and reconnected without cutting out a soldered fitting. Installations must comply with local plumbing codes and the relevant IAPMO PS117 press-fitting standard. The fitting ships individually, one piece per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect press union — no soldering, no torch required\u003c\/li\u003e\n\u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eRated from 0 degrees F to 250 degrees F operating temperature range\u003c\/li\u003e\n\u003cli\u003eLead-free copper construction for potable water compliance\u003c\/li\u003e\n\u003cli\u003eListed to IAPMO PS117 and NSF-61\/372 standards\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 1.252 inches for standard 3\/4-inch copper pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation press union for 3\/4-inch copper pipe systems in residential and commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off and depressurize the water supply line and verify the pipe end is clean, deburred, and within the allowable out-of-round tolerance before pressing. A calibrated press tool approved for the fitting series is required to achieve a proper seal — do not substitute pliers or uncertified tooling. Confirm all connections hold pressure before closing the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Press Fitting\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Press\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.252 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\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MB33010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51542128656690,"sku":"MB33010","price":55.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f782ee684a6f6f1db544c684d59601f.jpg?v=1785892954","url":"https:\/\/voomisupply.com\/products\/merit-brass-mb33010-copper-press-union-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
