I'm on the hunt for a way to connect my 4-inch dust collection hose to my benchtop machines, which have a 2.5-inch output. Most searches lead me to fittings that go the other way, like reducing from 4 inches to fit a smaller 2.5-inch hose (like those used for shop vacs). I'm hoping for something specifically designed for this purpose rather than just using a rubber sleeve. Any suggestions would be greatly appreciated! Thanks!

Check out Powertec for a great range of hoses and adapters. They have some nice fittings that might solve your problem! You can usually find better prices on Amazon or Walmart too. Here’s a link to their adapters page to help you get started: [Powertec Adapters](https://powertecproducts.com/dust-management/adapters-fittings/?srsltid=AfmBOorEDIx5-pFgYBhB2J0S1a8iGyyxJf1lE3EOoGfPalppke4ycONN).
You're running into trouble because the parts aren't typically sold to connect all the various components. It’s designed so that the tool’s port is meant to connect with a hose directly, like a male-female setup. Instead of going for a reduction fitting, consider getting a short hose that allows for a female-female connection. If you don’t have that, those rubber plumbing connections at hardware stores work well too and come with clamps to secure them!
That makes a lot of sense! I always thought it was just the manufacturers being annoying, but it really is about matching parts properly. Thanks for explaining!
