It prevents water intrusion at the roofline by forming a tight, weather-resistant barrier around the flue or vent stack. Constructed from galvanized steel, it resists corrosion and handles the temperature cycles common in residential and light commercial venting applications. HVAC technicians and plumbers install this collar as part of a complete venting assembly during new construction or reroof work.\u003c\/p\u003e\n\u003cp\u003eThis storm collar is suited for use with 3-inch vent pipes passing through roof decks, including B-vent and single-wall metal vent applications. It is a standard component in gas appliance venting systems such as furnaces, water heaters, and boilers. The collar seats over the flashing cone and is typically sealed with high-temperature silicone or roofing sealant to complete the weatherproof detail at the roof plane.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized steel construction provides corrosion resistance for outdoor roof-line exposure\u003c\/li\u003e\n  \u003cli\u003e3-inch nominal pipe size fits standard residential and light commercial vent stacks\u003c\/li\u003e\n  \u003cli\u003eDesigned to seal around the flue at roof penetration points, blocking water entry\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 6 units, suitable for multi-unit or contractor stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment storm collar for 3-inch round vent pipe assemblies in residential and light commercial venting systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or plumbers as part of a venting rough-in or service call. Before installing, shut down and allow the appliance and flue to cool completely. Slide the collar over the vent pipe above the flashing, then apply a bead of compatible high-temperature sealant around the top edge to ensure a watertight seal. Follow local building codes and the appliance manufacturer venting instructions for proper collar placement and clearance requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.57 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: GV1375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51563707990322,"sku":"GV1375","price":58.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/614e8debc1d3ad94894b76568ae58d62_f9da2706-09cc-4023-80f5-07a5d29bd92f.jpg?v=1786501802","url":"https:\/\/voomisupply.com\/products\/imperial-mfg-group-usa-inc-gv1375-galvanized-storm-collar-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
