AC Infinity Noise Reduction Clamps 4“ Duct Coupler with Stainless Steel Clamps - Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC

Rubber pipe couplings are designed to securely connect ducted components, preventing air leaks. The matte black rubber construction is flexible and heavy-duty, allowing it to easily fit over duct ports and piping. It minimizes noise by absorbing sound waves from fan vibrations and airflow traveling through the ductwork. The coupler creates an airtight seal and is held in place using adjustable stainless steel hose clamps with worm drive locks. This 4-inch coupler is suitable for inline fans and carbon filters with solid duct ports in growing and HVAC settings. The product description states that the rubber clamp is designed to connect duct ports securely, ensuring an airtight grip and preventing any loss of airflow. The nitrile butadiene rubber structure fits smoothly over ports and piping due to its flexible and adaptable build. The heavy-duty rubber construction also suppresses noise and vibrations by absorbing sound waves, creating a quieter growing or HVAC environment. For an even tighter connection, the stainless-steel fasteners with worm drive locks can be adjusted.
