A must to fit hoses
These are worth having around as they fit flexible hose and the rigid pipe of the vacuum systems. Add a little tape to the outside to prevent movement and you are set.

Excellent product.
The whole series of Rockler Dust-Right products seem to be very high quality and well made. More importantly, everything mates well with the appropriate products within the Dust-Right system. I no longer am trying to make do with cutting and taping fittings that almost fit. I have thrown it all out and gone to the Dust-Right system. Managing dust is now much more effective and fun!

Michael W on Jan 30, 2020
what is the outside diameter?
David H on Feb 15, 2016
BEST ANSWER: The ends where the hose slides over is four inches. The center area that gives it extra strength is four and one eighth
Will this work with the Blue 4" Dust Rite Hose?
Kevin O on Aug 6, 2017
BEST ANSWER: I do not have the Dust Rite system but a 4" connector should fit a 4" hose. Every other 4" connector I have bought from Rockler fits my 4" hoses.
How long is this connector?
John O on Dec 5, 2018
BEST ANSWER: I believe this connector is about eight inches in length.
Will the dust right handle fit over on of the ends? I have a sawstop table saw with the outfeed attachment. When it is in the collapsed position I cannot get the dust right handle through the rails far enough to get a good connection. I am thinking if I can extend the dust hook up out about eight inched then the handle won’t hit the rails on the outfeed table.
Richard W on Nov 6, 2019
I have (3) 4" hose sections that I'd like to have ends that can quickly connect/disconnect from the next hose in the line. Which part(s) are needed to make a quick splice in the line that can be disconnected easily and that section be stored for later use?
