Duct Reducter 6 to 4 Air Ducting Reducer Increaser Air Duct Adapter or Round Metal Pipe Reducer for Bathroom Kitchen Ventilation Systems

Exact size. Does not slide into fan housing duct. Although this doesn't work for me, the product is metal and good quality.

Awesome product, couldn't find in stores. Worked great

Perfect fit for my application. Very sturdy product. Packaged good.

For anyone trying to reduce the input and/or output of an 8" AC Infinity fan, these fit perfectly over the fan inlet and outlet. They fit so good you could probably get away without a tape seal. This was hard to tell if they would work, so I took a chance and these are cheaper than the AC Infinity ones that have mixed reviews on even fitting.

I dont know HVAC so this might be my fault. the end is exactly 6" & so was the output on my bathroom fan. So I had to crimp one in order to fit it in the other. Still worked.

It worked

Una union para reducir ductos o utilizarse en cualquier otro trabajo no puede tener esa medida. Si usted va a reducir de 6" a 4" se supone que la apertura del conector reductor en la boca de acople sea superior a 6" Usted no puede acoplar 6" exactas con 6" Eso lo sabe cualquier fabricante. Perdí el dinero. No perderé el tiempo en devolverlo. LA PIENZA NO ENTRÓ O ENCAJO EN LA SALIDA DEL EXTRACTOR. ME DUELE COMENTAR NEGATIVO EL ESFUERZO DE ALGUIEN AL VENDER ALGO. Si me entiende el vendedor y resuelve el problema ,Esta reseña la puedo modificar. Gracias.

Needed this for my ac unit. Fit good. No issues. As expected. I didn't want the plastic one so I got and liked this one.

All good

Fit perfectly, used it for fixing a upright air Conditioner

Could not find one in the hardware stores. Was able to find one here Amazon is great to find all that you need and don’t need It was good quality no issues

I purchased this 10" to 6" Air Duct Reducer and, overall, it got the job done. When it arrived, a few sections were slightly bent, so I had to straighten them out before installation. It also wasn’t a perfect fit, so my installer had to seal some gaps with foil tape to ensure there were no air leaks. Despite these minor issues, once everything was in place, the reducer functioned as intended. If you’re facing the same need to reduce from a 10" duct to a 6" duct, this product can certainly work—just be prepared to do a bit of tweaking and sealing. I’d still recommend it for anyone who needs a quick, reliable solution, as long as you’re aware you may have to make minor adjustments to get the best fit.

Good quality product. Fits correctly and a fraction of the cost of a big box hardware store.
