It features a rotating flange configuration with a press connection type, making it suitable for professional installation in closed-loop heating and cooling applications. The kit includes an isolator with drain, two full-faced flange gaskets, nuts, and bolts — providing the hardware needed for a complete flange-style circulator pump installation. The brass construction ensures durability in pressurized hydronic environments. Licensed plumbers and HVAC technicians working on residential or light commercial hydronic systems are the primary installers of this kit.\u003c\/p\u003e\n\u003cp\u003eThis kit is intended for use in hydronic circulator pump installations where a 3\/4 inch press connection is required. The rotating flange design allows for angular adjustment during pump alignment, simplifying installation in tight or confined mechanical spaces. The included drain-capable isolator enables pump service and removal without draining the entire system, reducing downtime during maintenance calls. The press connection eliminates the need for threading or soldering at the flange connection point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRotating flange design allows angular adjustment for easier pump alignment\u003c\/li\u003e\n  \u003cli\u003ePress connection type eliminates soldering or threading at the connection point\u003c\/li\u003e\n  \u003cli\u003eIsolator with drain enables pump removal without full system drain-down\u003c\/li\u003e\n  \u003cli\u003eKit includes two full-faced flange gaskets, nuts, and bolts for a complete installation\u003c\/li\u003e\n  \u003cli\u003eBrass construction for durability in pressurized hydronic applications\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch connection size suits common residential and light commercial circulator pump configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and installation kit for residential and light commercial hydronic heating circulator pump applications using 3\/4 inch press-style connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician familiar with hydronic system service. Shut down and depressurize the hydronic system before beginning installation, and allow components to cool if the system has been operating. Press connections require an approved press tool and the correct jaw size for 3\/4 inch fittings — verify tool and fitting compatibility before pressing. Follow applicable local plumbing codes and manufacturer torque specifications for flange hardware assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Flange\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Free\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: h-81413hvkit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51233891746098,"sku":"H-81413HVKIT","price":179.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307626778.jpg?v=1780111372","url":"https:\/\/voomisupply.com\/products\/nibco-h-81413hvkit-circulator-pump-install-kit-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
