Nice fitting for the chop saw.
I like this fitting for the chop saw along with a large pickup I call a big gulp.
Nice fitting to add to the chop saw along with a big gulp behind the saw.

good for table saw
I use this with table saw to provide two sources of dust collection. The larger diameter fits a bottom dust collection outlet and the smaller diameter is attached to the dust shroud. It works better than a single connection to just one of them.

Not much you can say about a piece of molded plastic
There's not much you can say about a piece of molded plastic. It would be nice, however, if the industry would get their collective act together on a fit standard and provide labeling with a consistent naming convention. That would eliminate a lot of frustration and multiple trips to find the appropriately sized molded plastic fitting. Of course that would also eliminate that box in your shop of misfit hose connectors and fittings.

I have a router with dust collection port but it doesn't help all the dust that fall around the bit. So with this I can run a second hose around to the bottom. Hopefully this will help.

James M on Sep 11, 2015
I chose this product because I am in the process of putting together a Dust Removal System in my woodworking shop. It has been my experience that Rockler stocks good reliable components for that task. I chose to buy from Rockler because they go out of their way to help me when I need advice. They have been my "Go To Supplier" for the last seven years. I can always depend on their products to be of the highest quality, just like their customer service.

Will the 4" to 2" y connection fit 4" sch. 20 sewer pipe?
A shopper on Jul 25, 2015
BEST ANSWER: It should. I used mine on schedule 40 with no problems. FYI Pipe measurements are ID(inside diameter) schedule refers to the wall thickness. Tubing measurement is OD ( outside diameter).
what is length of fitting 42253?
gordo on Jan 7, 2017
BEST ANSWER: The overall length is 10"
Is there an adapter to go from the 4 inch part of this to the dust right handle? I have the Y fitting on my table saw and want to be able to go from it to the floor sweep kit and that’s about it for now. Don’t want to have to rely on duct tape to make up the gap. The 4” fitting is really 3 7/8 and the dust right is way too big.

will the 4" connect directly to my dust collector or do I need a fitting to bridge the gap?
Martin C on Jan 7, 2017
BEST ANSWER: If you're connecting a 4" hose to the dust collector with this, the hose will connect to the 4" OD end of the elbow, and the flexible rubber end with the two hose clamps should seal onto the 4" OD inlet to your dust collector.
What is the outside dia. of these fittings ? I plan to use them on pvc pipe with a inside dia. of 4 inches.
Larry on Sep 3, 2016
BEST ANSWER: OD on mine measures 3 and 7/8 + about 1/32 or a little more. The fit on PVC was very loose for me...I had to bulk up this fitting with layers of tape to get even a little friction. Once caulked, though, it was airtight and stable. I found this piece fit very readily onto metal 4" ducting with no finagling.
Is this what I need to go from the Y to the dust right handle?
