Air Flow Products EC16 Tee End Cap 16 Inches

Product Description

The AIR FLOW PRODUCTS EC16 is a tee end cap designed to terminate the open end of a tee fitting in a duct or piping distribution system. At 16 inches, it provides a clean, secure closure that prevents airflow bypass and keeps the system operating as intended. Licensed HVAC technicians and sheet metal contractors install this type of fitting during new construction, system modification, or repair work when a tee branch requires capping. The EC16 is a straightforward mechanical component built for reliable service in standard air distribution applications.

This end cap is sized for 16-inch tee fittings and is suited for use in residential and light commercial HVAC ductwork systems. It is typically installed at the terminus of a branch tee where no downstream connection is needed, sealing off unused ports during system layout or future-proofing a distribution run for later expansion. The designation 88 in the product description may reference a fitting series or configuration relevant to the AIR FLOW PRODUCTS catalog.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handling unit and verify the system is depressurized before working on any duct fitting. Secure the end cap according to local mechanical code requirements, which typically reference SMACNA standards for duct construction and sealing. Seal all connections with code-approved mastic or foil tape to maintain system airtightness.
