Premium Build

Made with rugged ABS plastic, this hose connector is tough, highly durable and able to withstand the wear and tear commonly associated with abrasive and high volume use.

Compatible Size

Two 4 inch OD and one 2-1/2 inch OD y fitting nominal ends are slightly undersized to fit inside your 4” or 2-1/2” ID dust hose or port . Will not directly connect to other 4” or 2-1/2” OD ports.

4” Outer Diameter: 3-61/64” | Inner Diameter: 3-3/4”

Straightforward product that works well. I used this to split off a smaller section of dust collection hose from my main 4in line to a 2.5in line that leads to my miter saw. You obviously need hose clamps or tape to connect everything up, but this works well. The plastic seems thick and durable. Wish the price was just a touch lower since the price of all these different adapters in even a modest dust collection system really adds up, but otherwise good splitter.

Great quality and as expected. I use it on a sawmill dust discharge.

This worked great for my router table. Allows me to connect both dust collection ports into one house. Helps make one of the dirtiest tools in the shop not so bad.
