Rubber hose connector designed to securely couple ducted components together while preventing air leakage. The matte black rubber construction is flexible, sturdy, and can easily fit over duct ports and piping. Minimizes noise by absorbing sound waves from fan vibrations and airflow flowing through ducts. Creates an airtight seal and hold using adjustable stainless steel hose clamps with worm-drive locks. The 4 inch coupler fits inline fans and charcoal filters with solid duct ports in grow and HVAC settings.
