  • Not clean plastic welding at seams but functional
Style: 4" to 2.5" Y-Fitting (1pk)
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

  • Works !!
Style: 4" Cuff (1pk)
This was needed to connect my CNC to my wen dust extractor, had a 2 inch hose up to a 4 inch opening which has to connect to another 4 inch inlet on dust collector, both have 4” OD, and as you can see from pic, it worked perfectly. The thumb screws are a bonus, makes installing it a breeze. So if you’re looking for something to connect 2-4” hoses together, this is what you need . Arrived exactly when it said. Power tech is actually a decent company. Haven’t had to work with their customer service, so I cannot speak to that but their products are decent. ... show more

  • Inline vacuum door
Style: 2.5" Aluminum Blast Gate (2pk)
I chose these because of durability not realizing that the doors were so hard to open and so hard to close I would have sent them back and bought the plastic but I decided to keep them I give them three stars because the doors are so hard to operate.
