The C x M end configuration makes it suitable for connecting copper tubing to threaded pipe or equipment fittings in a single step. Cast from copper alloy conforming to ASTM B584, this adapter is built for pressure service in potable water, hydronic heating, and general plumbing systems. Licensed plumbers and pipefitters are the primary installers. At 0.16 pounds, it is a compact, single-piece component with no separate parts to manage on the job.\u003c\/p\u003e\u003cp\u003eThis adapter is used in residential and light commercial plumbing applications where a copper tubing run must terminate at a threaded male connection. Common scenarios include connections to valves, supply stops, gauges, and equipment inlets that accept a female NPT port. The sweat end accepts standard 3\/4-inch copper tubing, and the 3\/8-inch MNPT end threads directly into a compatible female-threaded fitting or body. It is appropriate for new installation and retrofit work alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast copper construction per ASTM B584 for pressure service durability\u003c\/li\u003e\n\u003cli\u003e3\/4-inch sweat (C) inlet to 3\/8-inch male NPT (MNPT) outlet in a single fitting\u003c\/li\u003e\n\u003cli\u003ePressure fitting style rated for use in pressurized plumbing systems\u003c\/li\u003e\n\u003cli\u003eMeets ASTM B584 and ISO standards for material quality\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.16 pounds for easy handling in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure fitting for copper sweat-to-male-NPT adapter applications in residential and commercial plumbing systems.\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 before beginning work. The sweat end requires standard flux and solder preparation of clean, dry copper tubing before torch application. The MNPT threads should be wrapped with thread seal tape or pipe joint compound before hand-tightening and final torque to the receiving female-threaded fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inches x 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x M (Sweat x Male NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B584, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B031250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51542337159474,"sku":"B031250","price":34.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39d00f297e79b2d432057400bb2bb722_c166b27a-84bc-4fbb-a8bb-0b08778faf31.jpg?v=1785898536","url":"https:\/\/voomisupply.com\/products\/nibco-b031250-cast-copper-adapter-3-4x3-8-c-x-m","provider":"Voomi Supply","version":"1.0","type":"link"}
