It mounts at the top of a Type B gas vent to block precipitation, debris, and downdrafts from entering the flue while still allowing combustion gases to exhaust freely. The snap-lock design allows for fast, tool-minimal installation without the need for sheet metal screws or special fasteners. At 4.83 pounds, this cap is sized for large-diameter residential and light-commercial venting applications. HVAC technicians and plumbers working on gas appliance installations or replacements are the typical installers.\u003c\/p\u003e\u003cp\u003eThis rain cap is suited for 12-inch Type B double-wall gas vent systems serving natural gas or propane appliances such as furnaces, boilers, and water heaters. The round profile matches standard round B-vent pipe terminations. It is appropriate for both new construction venting runs and service replacement on existing systems where the original cap has corroded, cracked, or gone missing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSnap-lock attachment for fast field installation without extra fasteners\u003c\/li\u003e\n\u003cli\u003eRound profile sized for 12-inch B-vent flue pipe\u003c\/li\u003e\n\u003cli\u003eBlocks rain, snow, and debris from entering the vent stack\u003c\/li\u003e\n\u003cli\u003eAllows unrestricted upward exhaust flow of combustion gases\u003c\/li\u003e\n\u003cli\u003eWeighs 4.83 pounds for stable, wind-resistant seating on the flue termination\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement rain cap for 12-inch round Type B double-wall gas vent systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber familiar with Type B venting requirements under NFPA 54 and the International Fuel Gas Code. Shut off the gas appliance and allow the flue to cool completely before working at the vent termination. Confirm the cap diameter matches the installed B-vent pipe size before seating. Follow the vent manufacturer instructions and local code requirements for minimum clearances at the termination point.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Snap Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.83 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12rc\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51233257357618,"sku":"12RC","price":221.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307628821.jpg?v=1780095596","url":"https:\/\/voomisupply.com\/products\/hart-cooley-12rc-b-vent-rain-cap-round-snap-lock-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
