Measuring 3\/8 inches in width and 300 inches in length, this cord is formulated to create a reliable, long-lasting seal around duct insulation, pipe insulation, and equipment panels. It is commonly stocked by HVAC technicians and insulation installers for both new construction and service work. The nonstaining formula means it will not discolor adjacent insulation materials or finished surfaces during or after installation.\u003c\/p\u003e\n\u003cp\u003eThis sealing cord is suited for residential and light commercial HVAC applications where insulation integrity is required. Typical use cases include sealing the edges of flexible duct insulation, wrapping around refrigerant line sets, and closing gaps at equipment cabinets or air handler penetrations. It is also used in mechanical rooms and utility spaces where a clean, non-messy sealant is preferred over tape or mastic in certain joint configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNonstaining formula will not discolor insulation or surrounding surfaces\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch width fits standard insulation seam and gap applications\u003c\/li\u003e\n  \u003cli\u003e300 inch length provides ample material per roll for multiple sealing points\u003c\/li\u003e\n  \u003cli\u003ePliable cord form allows hand-shaping to irregular surfaces and contours\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in HVAC insulation sealing without the need for mixing or special tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sealing solution for use with standard HVAC duct and pipe insulation systems in residential and commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians or insulation contractors as part of new system commissioning or service calls. Power down the air handling system before working in confined duct or air handler spaces. Press the cord firmly into the seam or gap to ensure full contact and adhesion with the insulation surface. No special tools are required, but surfaces should be clean and dry before application for best results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Insulation Sealing Cord\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 300 inches\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: NU-CALGON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NUCAL-4216-27\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NU-CALGON","offers":[{"title":"Default Title","offer_id":51383758815538,"sku":"NUCAL-4216-27","price":29.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670378.jpg?v=1782606547","url":"https:\/\/voomisupply.com\/products\/nu-calgon-nucal-4216-27-insulation-sealing-cord","provider":"Voomi Supply","version":"1.0","type":"link"}
