It creates a weather-tight barrier that prevents rain, debris, and wind-driven moisture from entering the building around the vent pipe. This component is a standard part of single-wall or B-vent chimney and venting installations and is typically installed by HVAC technicians, plumbers, or roofing contractors during new construction or vent system service.\u003c\/p\u003e\n\u003cp\u003eThis storm collar is suited for residential and light commercial applications where a 4-inch diameter vent or flue pipe exits through the roof. It fits over the vent stack and seats against the roof flashing to form a continuous moisture barrier. Typical applications include gas furnace venting, water heater flue terminations, and similar gravity or natural-draft venting systems that penetrate the roof deck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in outdoor and rooftop conditions\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter sizing for standard residential vent and flue pipe applications\u003c\/li\u003e\n  \u003cli\u003eSimple slip-on installation over existing vent stack and roof flashing\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 6 units, suitable for stocking or multi-unit jobs\u003c\/li\u003e\n  \u003cli\u003eLightweight design at 2.87 pounds per package for easy handling during roof installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation storm collar for 4-inch diameter single-wall galvanized flue pipes and vent stacks in residential venting systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified HVAC technician, plumber, or roofing contractor following local building codes and applicable venting standards such as the IFGC. Shut off the associated appliance and allow the flue to cool completely before working at the roof penetration. The collar should be slid down over the vent pipe and sealed to the flashing using a high-temperature, weatherproof sealant rated for outdoor rooftop use. Do not rely on the storm collar alone as the primary waterproofing element — proper flashing must be installed beneath it.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.87 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: IMPERIAL MFG GROUP USA INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GV1376\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51563760091442,"sku":"GV1376","price":58.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/614e8debc1d3ad94894b76568ae58d62_99053c3c-d281-4702-abd1-a0db8abfe3f9.jpg?v=1786502723","url":"https:\/\/voomisupply.com\/products\/imperial-mfg-group-usa-inc-gv1376-storm-collar-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
