Works very well.
Works very well and is a nice fit. It would get 5 stars if the plastic was more impact resistant like the attachment to the 4" pipe on my Record Power chip extractor but I still think it can take a bit of punishment without getting damaged. I'm not an expert but I think it's PVC rather than ABS.

4-Inch to 2-1/2 Inch Cone Reducer
At last, a cone reducer that fits a standard extraction pipe to a smaller pipe. Perfect!!! Shame I had to wait 8 days for it.

great value
I got this earlier than expected an it works great. It's well made and durable and fits perfectly. However I should ass make sure you read ALL of the description as I have seen some negative reviews for Bellends who gave negative reviews about not fitting and explaining in detail how they tried everything to make it work EXCEPT follow the directions. you need to by the rubber flex cuff to attach to your machines. As this is a solie plastic and so is the out port on your equipment I don't know how people can't understand that there would be no way to put a hose clamp (or duct tape on this) and tighten it. So I would say disregard any reviews complaining about fit and more on to others because it fitas fine and works great and I would highly recommend this product. BTW one last though make sure you know your inside diameter of the hose you are reducing to this doesn't fit many shop vacs but fits my grizzly table saw's overhead dust collection hose (it has a 4" port under the blade and a 2.5" hose coming off the blade guard) and this is because many shop vacs are NOT 2.5". Just measure your hose or check your operators manual for specs and order the correct one as they do offer several different and even universal ones

Be prepared to spend more money
Good product the only problem is is the inner diameter is not 100 mm or 4 inches which it should be to fit on to a dust extractor machine the inner diameter of this needs to be approximately 102 to 104 mm to fit onto a dust extractor it’s now cost me extra money to buy a sleeve to join this on to my dust extractor machine.
