Round Duct End Cap

The AD-ZK round duct end cap is designed for airtight sealing of round air duct ends in ventilation and air conditioning systems. It is used for temporary or permanent closure of air channels, during phased system installation, or to finish terminal sections of duct networks.
Using an EPDM rubber gasket significantly improves joint airtightness, reduces air leakage and pressure losses, and enhances overall aerodynamic and acoustic performance of the ventilation system.
AD-ZK end caps are manufactured from galvanized steel, ensuring durability, reliability, and easy installation.
