Air Flow Products EC12 Tee End Cap 12 Inches

Product Description

The AIR FLOW PRODUCTS EC12 is a tee end cap designed to close off the open end of a tee fitting in duct or piping distribution systems. Measuring 12 inches, this end cap provides a secure, finished termination point that prevents airflow bypass and keeps the system sealed. It is typically installed by HVAC technicians and sheet metal contractors working on ventilation trunk lines, branch takeoffs, or related air distribution assemblies. The 12-inch sizing suits commercial and residential applications where standard tee fittings require capping during phased installation or system modification.

The EC12 is suited for use in forced-air HVAC duct systems where a 12-inch tee fitting requires a sealed end. Common install scenarios include temporarily or permanently closing an unused branch port on a tee fitting, isolating a section of ductwork during renovation, or completing a balanced air distribution layout. The part designation 88 indicates a specific tee series for which this end cap is sized and matched.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling system and ensure the fan is off before accessing ductwork. Verify that the end cap seats flush and is secured according to local mechanical code requirements before restoring airflow. Do not operate the system with an unsecured or improperly fitted end cap, as this can cause air leakage and reduced system efficiency.
