It measures 1 inch by 3\/4 inch by 72 inches and features 18 outlet ports. This manifold is a core component in radiant floor heating, baseboard heating, and hydronic loop systems used by plumbers, HVAC technicians, and mechanical contractors. The header pipe diameter is 4 inches, and the port connections are 1 inch by 3\/4 inch, making it compatible with a wide range of zone valves, circulators, and radiant tubing setups. The plain end connections allow for flexible installation using standard soldering or press-fit fittings, depending on the installer's preference and system requirements. Copper construction ensures excellent thermal conductivity, long-term corrosion resistance, and reliable performance in both potable and closed-loop hydronic systems. With 18 outlets, this header is well suited for large residential, light commercial, or multi-zone mechanical rooms where multiple heating or cooling circuits must be managed from a single supply or return manifold. Zone headers like this one simplify piping by consolidating multiple circuit connections into one central distribution point, reducing overall pipe runs and improving system efficiency. The 72-inch length provides generous spacing between outlets, making it easier to connect zone valves, ball valves, or flow meters without crowding. This product is commonly used alongside boilers, heat pumps, and thermal storage tanks in closed hydronic systems. HVAC and plumbing professionals rely on copper zone headers for their durability, ease of fabrication, and compatibility with standard hydronic fittings and components. The Precision php-100018750-4 is a dependable choice for any large-scale hydronic distribution application requiring multiple independently controlled zones.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e18 outlet ports for multi-zone hydronic distribution in large residential or light commercial systems\u003c\/li\u003e\n\u003cli\u003eFull copper body construction for superior thermal conductivity and long-term corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePlain end connections allow soldering or press-fit installation with standard hydronic fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Precision php-100018750-4 copper zone header delivers 18-zone hydronic distribution in a 72-inch copper manifold, built for high-demand radiant and hydronic heating systems requiring reliable, multi-circuit flow management.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: php-100018750-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Hydronic Manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1 inches x 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Pipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ports\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION","offers":[{"title":"Default Title","offer_id":51120809247026,"sku":"PHP-100018750-4","price":27.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881435.jpg?v=1777740148","url":"https:\/\/voomisupply.com\/products\/precision-php-100018750-4-copper-zone-header-1-inches-x-3-4-inches-x-72-inches-18-outlet-4cc","provider":"Voomi Supply","version":"1.0","type":"link"}
