This wall band holds vent pipe securely against an exterior wall, preventing movement and keeping the venting system properly aligned. It is part of the Selkirk RV line, which is built for residential, light commercial, and light industrial gas appliance venting applications. HVAC technicians and installers rely on wall bands like this one to maintain code-compliant vent installations where pipe runs along an outside wall surface. The 104431 fits 4-inch RV pipe, which refers to the inside diameter of the pipe. The outside diameter of RV series pipe is approximately 4.5 inches due to the double-wall construction. The outer shell is made from 28-gauge galvanized steel, and the inner liner is aluminum, giving the system both durability and corrosion resistance in venting environments. Proper installation requires placing the wall band just above the tee fitting and then repeating every 6 feet along the pipe run. This spacing prevents sagging, vibration, and lateral movement that could compromise the integrity of the vent system over time. Type B gas vent pipe is used with natural gas and propane appliances such as furnaces, boilers, water heaters, and unit heaters. The RV series is a round vent format suited to a wide range of standard gas appliances in residential and commercial settings. Using the correct wall support hardware is essential for passing inspection and ensuring long-term vent system performance. The Selkirk 104431 is a direct-fit component within the RV product family, also referenced as part number 4RV-WB.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStabilizes 4-inch Type B RV gas vent pipe against exterior walls\u003c\/li\u003e\n\u003cli\u003eMust be installed just above the tee fitting and every 6 feet along the pipe run\u003c\/li\u003e\n\u003cli\u003eCompatible with the Selkirk MetalBest RV line for residential and light commercial gas appliance venting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 104431 RV Wall Band provides secure lateral support for 4-inch Type B gas vent pipe runs along outside walls, helping installers meet spacing requirements and maintain a safe, stable venting system.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SELKIRK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 104431\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size (Inside Diameter)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate Outside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Material\u003c\/strong\u003e: 28-gauge galvanized steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Liner Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Round Gas Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Spacing\u003c\/strong\u003e: Just above tee fitting, then every 6 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential, light commercial, and light industrial gas appliance venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MetalBest RV\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SELKIRK","offers":[{"title":"Default Title","offer_id":51120849486130,"sku":"104431","price":45.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881658.jpg?v=1777741359","url":"https:\/\/voomisupply.com\/products\/selkirk-104431-rv-wall-band-4-inches-4rv-wb","provider":"Voomi Supply","version":"1.0","type":"link"}
