The Selkirk 2003623 is a 10 inch Model R Type B Gas Vent 45 Degree Elbow designed for large diameter venting applications in residential and commercial gas appliance installations. This elbow fitting allows HVAC installers and plumbers to offset a vent run and route it around obstructions such as rafters, joists, and structural framing members. Without a reliable elbow like this, a straight vent run would be impossible to complete in tight or congested attic and wall spaces. The 2003623 fits into the Selkirk Model R Large Diameter Type B Gas Vent system, which is engineered specifically with the installer in mind. The system features lightweight construction and a small footprint, making it a practical choice when working in confined spaces where maneuverability is limited but venting performance cannot be compromised. Type B gas vent is the industry standard double-wall vent used to exhaust flue gases from natural gas and propane appliances such as furnaces, boilers, water heaters, and unit heaters. The inner wall of a Type B vent is aluminum and the outer wall is galvanized steel, and the air space between the two walls insulates the flue gases to maintain proper draft and reduce the risk of condensation. The 10 inch diameter version of this elbow is adjustable from 0 to 45 degrees, giving installers the flexibility to fine-tune the angle of the offset on the jobsite without cutting or fabricating additional components. This adjustability reduces material waste and speeds up the installation process. The elbow connects securely to other Model R components for a tight, dependable fit that meets Type B gas vent installation requirements. HVAC technicians and mechanical contractors working on large commercial or residential venting jobs will find this fitting reliable and easy to work with.
The Selkirk 2003623 provides a code-compliant, adjustable 45 degree offset solution for 10 inch Type B gas vent systems, giving installers the flexibility and reliable fit needed to complete large diameter venting jobs efficiently.
