  • Fits DustRight 2.5 hoses no problem
Usually powertec does not fit Rockler DustRight hoses but this fit my 2.5 inch DustRight hoses just fine. Works like a champ and didn’t have to modify anything to fit properly

  • Works great
I got this today and ran it to my shop to finish my last dust collection run. It’s built well and fit exactly like I needed. Powertech makes great stuff and I’ve never had an issue.

  • Not clean plastic welding at seams but functional
Unlike other dust collection fitting from Powertec, this splitter/fitting has obvious plastic welding at the seams with blobs of plastic sticking out inside. I did not see this in my other Powertec fittings - I have several, but this one does have the most complicated shape. One reviewer commented that the fitting arrived with cracked at the seam, so little concerning. Nevertheless, I installed it and appear to be working well. I will update for a more long term review. ... show more

  • Decent item
Wish the pipe angles were 45 degrees rather than 30 degrees, but it meets my needs. Well made.

  • It's not 4 inches
Went and bought a 4 inch rubber coupler and it didn't fit, it was too big. I had to use a 3 inch coupler and made it fit. Measured the powertec splitter and its 3.65 inches.
