The Selkirk Type B Gas Vent with 3-Inch Diameter and 90-degree Adjustable Elbow (Model RV) is engineered for safe, efficient venting of Category I gas appliances such as furnaces, water heaters, and boilers. This high-performance venting component is designed to simplify installation while ensuring lasting reliability and compliance with safety standards. Built with a durable aluminum inner liner and a galvanized steel outer wall, the RV elbow offers a double-wall construction with a uniform 1/4-inch air space, providing excellent insulation and promoting rapid warm-up for improved draft. This construction also helps reduce condensation while maintaining a 1-inch clearance to combustibles, enhancing fire safety during operation. The standout feature of this model is Selkirk's patented Lock-Tab locking system, which offers 360-degree flexibility for seamless directional adjustment and alignment. The Snap Lock coupler with an optional Lock Tab ensures a secure, gas-tight connection with every installation. The die-formed male end eliminates sharp edges for safer handling and a smoother fit with adjoining components. Designed for precision and ease of use, this adjustable elbow is ideal for navigating tight spaces or directing vent flow through 90-degree angles. Whether you're retrofitting or building new, the Selkirk Type B Gas Vent elbow delivers professional-grade performance, safety, and installation convenience in one reliable package.
