## 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.

Review: Sehr gut verarbeitet, und passt genau
Review: At first glance this may seem expensive. I bought two to mount my inline duct fan - same brand S6. These made the install simple as they slip along the duct allowing the fan to be inserted in the gap. Then they both slide back to engage with the fan before tightening the supplied clamps. The fan didn’t require any other support or fixings and the rubber deadens any vibration. There was no noise from this installation other than air movement based on how much air was moved. See my review of the S6 fan which is excellent. Final thought - the presentation in terms of the packaging was excellent.
