Rockler 4'' to 2-1/2'' Dust Collection Y-Connector

This fitting provides two functions that could normally only be achieved by purchasing multiple fittings and hoses—a significant cumulative expense. Firstly, it splits the main line into two lines with an efficient, clog-resistant ''Y'' junction. Secondly, it reduces the hose diameter from a single 4'' hose to two 2-1/2'' hoses so you can connect to common power tools that have a smaller port size, among them router tables, band saws, and small table saws. The 2-1/2'' ports are also compatible with our Universal Small Port Hose Kit, so you can connect handheld power tools to your dust collection system.


Tip: For maximum dust collection efficiency, hose reducers should be located as close to the power tool(s) as possible.

Just what I needed!
I have a 4" main duct in my dust collection system and I wanted to collect dust from my router table from both above and below. This connector allowed me to do that easily by splitting the 4" drop into two 2" connections.

saved a lot of fittings
It was a new item I saw in catalog as I was planning an addition for my smaller wood tools like boss sander and router table. It saved me from figuring out what I needed to go from the 4 inch hose to using standard reducing fittings. The 2 1/2 inch hose was pretty easy to slip on and fits tight.

Some of the reviews here makes me wonder about people's skillset...why would you try and mate this without duct tubing lol. The product works how it is intended.

Saves time, space and money
Great way to combine a couple of fittings in one. The only draw back is a tiny gap where the two sides of the molding come together. This is pretty nit-picky, and can be easily cover with a bit of tape.

Read the discription carefully
I was thinking that the "connector" would fit into, or over the 4" inlet on my dust collector. it doesn't. On re inspection of the picture I see that You are required to buy a section of 4" hose and clamps, or purchase some other adapter to use this Y-connector. Annoying at best.

Requires coupler
Same size as intake. Requires a coupler to attach to intake pipe. Cheap fix but can't see why it's not made to fit over intake pipe.

Does the 4" end fit a dust right handle.?
Keith S on Jan 4, 2017
BEST ANSWER: No. The dust right handle fits over the the 4" end ov the Y, but it is very loose with about 1/8 to 1/4 inch gap. You will need the 4" dust right quick connect to make it work correctly.
How to close off one end when you are not using the tool?
Ken R on Jun 25, 2018
BEST ANSWER: The way that I separated each leg of this Y was to use blast gates on each leg. Search 26560 on the Rockler site and that should get you to what I used.
"The 2-1/2'' ports are also compatible with our Universal Small Port Hose Kit". Can you clarify how? I would love to connect two of my 1.5" hoses to this.
