## Overview

The AC Infinity Noise Reduction Clamp is a 4-inch flexible rubber duct coupler with adjustable stainless steel clamps designed to create an airtight, noise-minimizing connection for inline fans and carbon filters.

## Description

Product DescriptionA rubber clamp designed to connect duct ports with a secure and airtight grip to prevent any loss of airflow. The nitrile butadiene rubber structure fits smoothly over ports and piping thanks 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. To ensure an even tighter connection, you can adjust the stainless-steel fasteners with worm drive locks, which are built into ribbed grooves along the rubber clamp to lock it in place. When using flexible couplings to attach ducted components, this rubber coupler guarantees an effortless installation and long-lasting fit.ApplicationsThis matte black coupler fits securely over ducting and piping components. Its durable rubber design prevents air leaks and reduces noise in grow rooms, grow tents, and HVAC settings. This simple and effective clamp provides the perfect support for ducting, carbon filters, inline fans, mounting grilles, dampers, and more.
