If you have an 8 inline fan and filter that you want a practically airtight and quiet connection, then this AC Infinity Noise Reduction Clamp 8-Inch, Duct Coupler with Stainless Steel Clamps will do just that and look professional and neat in the process. Made from quality materials and simple to install, do not hesitate to pick up this great accessory for your growing needs!

Now that product has actually arrived I can properly review it. Connector hose is a tight fit but you want that. So as a result it is a little difficult getting it seated on both ends. Product does work as advertised. I liked it so well I have ordered 2 more so I can make all fan to device connections. I do recommend this product.

For what you charge for your fans, these should come with them.

I used a couple of these to connect a high-CFM duct fan into 8 metal ducting. Years ago I had installed a pop-up vent behind our kitchen center-island cooktop, but I never got around to installing a fan to vent it outside. In the process of finishing our basement, I decided I should probably get that done before installing drywall and buttoning up the ceiling below the main-floor kitchen. I used standard 8 HAVC ducting to route the vent, and purchased a Vortex VTX800 duct fan here on Amazon, and then had to find a way to connect the fan into the ducting without transmitting vibration from the fan into the ducting. Standard 8 rubber couplers are not 8, as they are made for connecting to PVC and similar pipe with an outside diameter larger than 8. These AC Infinity couplers, however, are exactly 8 inside diameter, and while theyre a little shorter than I would have preferred, they worked perfectly. Theyre a little costly for the material you get, but I dont know that theres anything else this size out there, so this was a great find. Thank you Amazon!

Easy to install and helps with vibration and noise.

Works well does the job

This duct coupler works perfectly! It fits perfectly creating an air tight seal and noticeably reduces noise. I highly recommend it.

Its a well thought out piece for the ac infinity inline unit. Although not necessary, it adds a clean look to the grow tent.

Fit both fan and filter reduced noise and sealed it up nice

Works great. Well packaged.
