Worked for my purpose
I needed a method for blowing accumulated crap off the top of my gutter guards from the ground. I bought a Worx gutter pro kit on Amazon ( used like new for half original price) and needed a way to attach it to my Milwaukee blower. This part from Spectre worked exactly as I had hoped. It is flexible enough to stretch it over the end of the blower tube which will remain on the blower. The small end slips over the Worx pipe snugly, but not so tight that you can’t install it in under a minute. Works like a charm.

Good solution for Makita 2012NB planer
My Makita 2012NB thickness planer has a nonstandard dust port. This coupler enables me to attach a standard 2.5" shop vac hose to it. It's not a perfect fit but it's definitely a workable solution.

like all spectre products this is really good quality
like all spectre products this is really good quality. it worked on my carb for my jeep. it is kinda tall so the hood hit the hose for it a bit, but it is a good quality item that came in fast and has lasted years. wanted to wait a while before writing anything to see how well this worked. so if your making a cold air intake this is acceptable for the job.

Great quality
Made of good material and the clamps are made well too. Was $10 cheaper on amazon than it was at my local auto store for half the price. Holding 10psi of boost with ease. A++

Worked
Used two of these on a JEGS hot road heater in my jeep, the duct hose is 2.5" and the openings on the heater are 3" for reasons unknown. Worked great, had to trim one down and was easily done with a razor blade.
