This component is part of the Selkirk MetalBest RV line, a round Type B gas vent system engineered for residential, light commercial, and light industrial applications where approved gas appliances require reliable exhaust venting. The 107082 is a 12-inch nominal length unit that adjusts from 3.5 inches to 10.5 inches, giving installers the flexibility to hit an exact required vent length without cutting pipe or adding unnecessary fittings. When used in combination with a standard straight length section, this adjustable piece ensures that the total vent run meets precise measurement requirements on the first install. The fitting also allows for easy disassembly after installation, which simplifies future service and inspection. Just as important, it is designed to absorb linear thermal expansion that occurs in longer vent pipe runs. Gas vent systems heat up and cool down with every appliance cycle, and that movement puts stress on rigid connections. The adjustable design gives the pipe room to move safely. The inside diameter of this fitting is 7 inches. The outside diameter is approximately 7.5 inches, which is roughly 0.5 inches larger than the stated size, a standard RV line dimension that installers should account for during planning. The outer shell is constructed from 28-gauge galvanized steel for corrosion resistance and structural durability. The inner liner is aluminum, a material well-suited for gas vent applications because it resists the acidic condensate that can form in Type B vent systems. HVAC technicians, plumbers, and mechanical contractors working on gas furnaces, boilers, water heaters, and similar appliances will find this fitting compatible with the broader Selkirk RV vent system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdjustable from 3.5 inches to 10.5 inches for precise vent length fitting\u003c\/li\u003e\n\u003cli\u003eAbsorbs linear expansion in longer vent pipe runs, reducing stress on connections\u003c\/li\u003e\n\u003cli\u003eOuter shell is 28-gauge galvanized steel with an aluminum inner liner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Selkirk 107082 adjustable length fitting gives installers exact control over vent run length while accommodating thermal expansion, making it a reliable component for Type B gas vent systems in residential and light commercial applications.\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: 107082\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: 7RV-AJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Gas Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment Range\u003c\/strong\u003e: 3.5 inches to 10.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter (Approximate)\u003c\/strong\u003e: 7.5 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\u003eApplication\u003c\/strong\u003e: Residential, light commercial, and light industrial gas appliance venting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SELKIRK","offers":[{"title":"Default Title","offer_id":51121072963890,"sku":"107082","price":58.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881628.jpg?v=1777747597","url":"https:\/\/voomisupply.com\/products\/selkirk-107082-rv-adjustable-length-type-b-gas-vent-pipe-7-inches-12-inches-7rv-aj","provider":"Voomi Supply","version":"1.0","type":"link"}
