I searched for a long time to find the best solution to connect my dust collector / shop vac to my Dewalt DW745 table saw. I couldn’t find an appropriate plastic adapter/attachment locally. This silicone intercooler piping reducer goes from 2 1/2″” to 1 3/4″ (45mm – 63mm interior diameter). A perfect fit for my shop vac hose: No hose clamps needed, it doesn’t take a lot of room and it’s pretty cheap too! I have been using it for the last 2 years without any problems. I hope this tip will save you a lot of time, so you can get back to building projects. This solution is a nice upgrade that should work on other jobsite table saw brands like Ridgid, Ryobi, Milwaukee, Delta, Hitachi, Bosch, Skilsaw, Sawstop or Makita as long as they have 2.5″ dust ports (DWE7485, DWE7491X, DCS7485T1, DCS7485B) . Thanks for watching!

    Hated the video but still liked it.

    Amazon is showing it as $11.95, but shipping is a crazy $200 to get it to New Zealand. I wonder if you can find it direct from China via Bangood or Wish?

    Great idea!

  4. Jsk C. on April 19, 2022 at 6:20 pm

    Geez it’s a pain in the ass to find the proper adapters. Thanks for this video

    Where is the link?

  6. banto on April 19, 2022 at 6:25 pm

    Thanks a million!. Been looking for an adapter for a few years now. Found a 2.5" to 2" reducer on ebay for $5.30 incl shipping.

    now i have to debate patience with winter coming or impatience cuz that’s just me! thanks for this! i would assume something equivalent for the dewalt mitre saw where the outport is smaller than the rigid vac?

  8. Cad1900 on April 19, 2022 at 6:32 pm

    Thank you this is a perfect solution!!!

  9. Javier Cardo on April 19, 2022 at 6:37 pm

    Any home store should have them. I used a 2′ x 1/2 in. PVC flexible coupling

  10. Brian Heuer on April 19, 2022 at 6:37 pm

    Now I just need an adapter that goes from the dewalt table saw to 4inch that my quick connect will work on.

  11. Louise Lafrenière on April 19, 2022 at 6:43 pm

    You are a genius thank you so much!

  12. Maydanlex on April 19, 2022 at 6:47 pm

    I may have missed it but what shop vac were you using? I have a Dewalt ShopVac and I’m looking at purchasing the Dewalt Table Saw. Subscribed!!!

  13. David-Etienne Bouchard on April 19, 2022 at 6:52 pm

    Exactly what I needed, et avec exactement le même accent que moi en anglais. Merci!

  14. MC2 Productions on April 19, 2022 at 6:55 pm

  18. Judy Konopka on April 19, 2022 at 7:04 pm

    THANK YOU! It’s not because you live in Canada, we have the same problem in the US!

  19. Tim List on April 19, 2022 at 7:05 pm

    I need one to go from the 2.5 inch on the dwe7485 to a 1-1/4 stanley shop vac. Any suggestions?

  20. Gregory MacNeil on April 19, 2022 at 7:08 pm

    Thank You! Got mine from China via Ebay as you suggested. Perfect fit. Delivery was only 4 weeks – So I earned $5 per week for being patient.
