The Selkirk 105180 is a 5 inch Steel Gas Vent Tee Cap designed for Type B gas vent systems. It fits at the bottom of a tee section and serves as a removable access point for inspection, cleaning, and routine maintenance. HVAC technicians and gas appliance installers rely on tee caps like this one to keep vent systems clean, accessible, and performing correctly over time. This cap is made from galvanized steel, giving it strong resistance to corrosion and the ability to hold up under the heat and moisture conditions common inside gas vent systems. The 550 degree F temperature rating makes it well suited for the thermal demands of natural gas and propane appliance venting. Type B gas vents are approved for use with Category I gas appliances, including furnaces, boilers, and water heaters that operate with a non-positive vent pressure and flue gas temperatures that will not condense under normal conditions. The tee cap plays a key role in this system by sealing the bottom of the tee while still allowing easy removal when the vent needs to be inspected or cleaned out. Removing debris and condensate from the tee is a standard maintenance step, and this cap is designed to make that task simple. The Selkirk 105180 measures 5 inches wide and 5 inches deep, with a height of 0.5 inches, making it a low-profile component that fits neatly into the vent assembly. It is made in the USA and carries a limited lifetime warranty. TAA and BAA compliant. A single cap is included per package.
The Selkirk 105180 provides a durable, easy-to-remove tee cap solution for 5 inch Type B gas vent systems. Made in the USA with a limited lifetime warranty, it is a dependable choice for HVAC installers and service technicians.
