With a 1-1\/2 inch fitting size and copper-to-copper (C x C) end connections, it is built for sweat-soldered installations where a watertight seal at a tank wall, vessel, or partition is required. The pressure fitting style ensures the joint meets system pressure demands without relying on threaded or mechanical retention alone. Manufactured from cast copper and rated to ASTM B584 and ISO standards, this fitting is a reliable choice for professional plumbing and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and light commercial plumbing applications where a piping run must pass through a wall, tank, or structural panel. Typical install scenarios include water storage tanks, pump sumps, water treatment enclosures, and similar pressure systems. The C x C end connections accommodate standard copper tube joined with sweat solder, making it straightforward to integrate into existing copper distribution systems. Licensed plumbers and pipefitters are the primary installers for this type of fitting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast copper construction meets ASTM B584 and ISO standards for material integrity\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch fitting size with C x C end connections for sweat-solder installation\u003c\/li\u003e\n\u003cli\u003ePressure fitting style rated for pressurized copper piping systems\u003c\/li\u003e\n\u003cli\u003eBulkhead design provides a through-wall seal for tanks, vessels, and panels\u003c\/li\u003e\n\u003cli\u003eSingle-piece cast construction for consistent wall thickness and joint strength\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 1-1\/2 inch copper pressure piping systems using sweat-solder C x C end connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the system, and drain all water from the line before cutting in or removing a bulkhead fitting. Clean and flux all copper mating surfaces thoroughly before applying heat; overheating cast copper fittings can compromise joint integrity. Ensure the bulkhead locknut is properly tightened against the panel wall before making final sweat connections.\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: 1-1\/2 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 C\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: 2.87 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: B350500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51543121428786,"sku":"B350500","price":346.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dddbbb2ba9f0bb05e255beadefc9bd08_f037ded0-ad99-4a6e-829e-9b381402cbea.jpg?v=1785915979","url":"https:\/\/voomisupply.com\/products\/nibco-b350500-cast-copper-bulkhead-fitting-1-1-2-in-c-x-c","provider":"Voomi Supply","version":"1.0","type":"link"}
