Duravent 0790ELL B-vent 90 Degree Adjustable Elbow 7 in

Product Description

The DURAVENT 0790ELL is a 90-degree adjustable elbow designed for Type B gas vent systems with a 7-inch diameter. It allows installers to redirect vent runs from vertical to horizontal or to navigate obstructions during vent routing. The adjustable design provides flexibility in achieving precise angles within the 90-degree range, reducing the need for multiple fittings on complex installations. Licensed HVAC technicians and gas appliance installers use this fitting when routing natural gas or propane appliance exhaust through walls, attics, and mechanical chases in residential and light commercial applications.

This elbow fits into Type B double-wall vent systems, which are commonly used with gas furnaces, water heaters, boilers, and other Category I gas appliances that require a listed venting product. The 7-inch diameter makes it suited to mid-to-large capacity appliances where the vent connector size is specified by the appliance manufacturer or determined by manual J or vent sizing tables. It integrates with standard DVP series Type B vent components for complete system assembly.
