Selkirk 108100 Type B Gas Vent Rv Tee 8 Inch

Product Description

The SELKIRK 108100 is an 8-inch RV Tee fitting for Type B round gas vent systems. It transitions the vent run from a horizontal orientation to vertical, allowing the system to rise toward the terminal. The fitting is part of the MetalBest RV line, which uses a 28-gauge galvanized steel outer shell and an aluminum inner liner. Licensed HVAC technicians and plumbers install this fitting during gas appliance venting work in residential and light commercial applications. The tee cap is sold separately and should be sourced when ordering this fitting. Inside diameter is 8 inches; outside diameter is approximately 8.5 inches.

The 108100 is designed for approved gas appliance venting in residential and light commercial and industrial settings. It suits installations where the vent run must change from horizontal to vertical, such as mid-run offsets on water heaters, furnaces, or boilers connected to Type B round vent systems. The accessible tee body also supports inspection and maintenance of the vent interior without full system disassembly. This fitting is part of the broader MetalBest RV product line; large-appliance round vent components are found in the QC line instead.
