At 1\/2 inch in size with sweat-style C x C end connections, it allows copper tubing to pass through a barrier while maintaining a sealed, pressure-rated joint on both sides. Weighing 0.48 pounds, the fitting is machined from cast copper and conforms to ASTM B584 and ISO standards. It is installed by licensed plumbers and HVAC technicians wherever a watertight bulkhead penetration is required in copper piping systems.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial plumbing, HVAC, and hydronic applications where a 1\/2 inch copper line must penetrate a tank shell, reservoir wall, or equipment panel. The C x C configuration accepts standard copper tubing on both ends, making it compatible with conventional sweat-soldering workflow. It is commonly used in water heater connections, expansion tank installations, and custom fabricated equipment panels that require a pressure-rated through-fitting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast copper construction meets ASTM B584 and ISO standards for pressure service\u003c\/li\u003e\n\u003cli\u003e1\/2 inch fitting size with C x C (sweat) end connections on both sides\u003c\/li\u003e\n\u003cli\u003eBulkhead design allows sealed copper tubing penetration through tank walls or panels\u003c\/li\u003e\n\u003cli\u003ePressure fitting style rated for standard service pressure requirements in copper systems\u003c\/li\u003e\n\u003cli\u003eCompact, single-piece cast body for consistent wall thickness and joint integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation bulkhead fitting for 1\/2 inch copper tube systems using sweat (C x C) connections in pressure plumbing and HVAC applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician following applicable IPC and local plumbing codes. Shut off and drain the system before cutting into any live line or modifying a tank wall penetration. Use standard sweat-soldering tools and lead-free solder compliant with potable water requirements where applicable. Ensure the bulkhead nut is tightened to the tank wall before making final solder joints to avoid heat transfer damage to sealing surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bulkhead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x C (Sweat)\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\u003eStandards\u003c\/strong\u003e: ASTM B584, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B350300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51542399811890,"sku":"B350300","price":132.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dddbbb2ba9f0bb05e255beadefc9bd08_d0c9a119-6aea-452b-8911-1f327fd95639.jpg?v=1785899694","url":"https:\/\/voomisupply.com\/products\/nibco-b350300-cast-copper-bulkhead-fitting-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
