This component provides a clean, secure closure that prevents airflow leakage and maintains system pressure at unused tee outlets. It is commonly installed by HVAC technicians and plumbers during new construction or retrofit work where a tee branch is not yet connected or is being permanently capped off. The EC03 is a straightforward mechanical component suited for residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe EC03 fits 3-inch tee fittings and is appropriate for use in branch duct systems, piping networks, or distribution manifolds where an unused outlet requires a reliable end cap.
