Selkirk 103100 3-inch Type B Gas Vent Tee Double Wall Round Standard 3RV-TS

Product Description

The Selkirk 103100 is a 3-inch Type B gas vent tee designed for residential, light commercial, and industrial venting applications. It is part of the Selkirk RV series and carries the LOCKTAB connection system for secure, reliable assembly. This double wall round vent tee is built to handle the exhaust gases produced by gas-fired appliances such as furnaces, boilers, water heaters, and unit heaters. Type B gas vent systems are specifically designed to vent Category I appliances that produce non-positive vent pressure and flue gases at relatively low temperatures. The tee fitting allows installers to branch a vent run or create cleanout access points within a venting system. It is a standard component used by HVAC technicians, plumbers, and mechanical contractors when roughing in or servicing gas appliance venting systems. The Selkirk 103100 features an inner liner constructed from aluminum alloy at 0.012 inches thick, which resists corrosion from condensate and flue gas contact. The outer wall is made from G90 galvanized steel at 0.018 inches thick, providing structural durability and protection against mechanical damage. The double wall construction also provides an insulating air space between the inner and outer walls, which helps maintain flue gas temperature and improves draft. The fitting measures 3 inches by 3 inches by 3 inches, making it a direct fit for 3-inch Type B vent systems. It meets UL 441, CAN/ULC S605, CSA B149, and NFPA 54/211 standards, ensuring code compliance on permitted installations across the United States and Canada. Professionals working on gas appliance venting, Type B vent installation, or vent system repairs will find this tee a dependable, standards-compliant component.
