The AIR FLOW PRODUCTS EC08 is a tee end cap designed to terminate or close off the open end of a tee fitting in an 8-inch duct or pipe assembly. This fitting provides a clean, secure closure at tee junctions where one branch of the tee is unused or capped during installation. It is a standard component in air distribution and ventilation system configurations. HVAC technicians and sheet metal installers typically work with this type of fitting during duct system fabrication and modification.
The EC08 tee end cap is suited for use in residential and light commercial HVAC ductwork where 8-inch tee fittings are present. It is commonly installed when a tee branch is not needed for active airflow but must be sealed to maintain system pressure and prevent air leakage. This fitting is appropriate for new construction and retrofit duct installations alike.
Designed as an OEM-style end cap for use with 8-inch tee fittings in residential and light commercial air distribution duct systems.
Installation should be performed by a qualified HVAC technician or sheet metal installer. Power down the air handling unit and any associated equipment before working on the duct system. Ensure the end cap seats fully and securely on the tee fitting, and seal the joint with appropriate duct sealant or tape per applicable mechanical codes to prevent air bypass.
