This tee cap provides a reliable closure for 4-inch Type B vent systems, commonly used with natural gas or propane appliances. Its design ensures a secure fit, preventing leaks and maintaining the integrity of the exhaust pathway. It's an essential accessory for completing a professional and compliant B-vent installation.
