Fulton 4 inch to 2 1/2 inch Reducer Fitting for Dust Collection Hose to Hose Connections and 4 Inch Port Connections on Larger Machinery

As described works great

¡Excelente compra! Cumple con las especificaciones publicadas.

I bought a new saw that didn't have a 4 inch dust collector port. This was perfect. It accepts a 2 1/2inch hose inserted the same way you would insert a brush or a blade fitting on a shop vac. It's a male 4 inch fitting with a female 2 1/2 inch fitting. Well made, works well.

It’s a hard plastic reducer. True to size with no defects.

So many BIG tools and devices use 4" but my small shop mostly needs 2 1/2" or smaller. This transition works well because it is tapered. I use it to transition from the big gulp under my table saw to the 2 1/2" hose further down the line in my system. It seems to easily keep suction even with the reduction in size. Some dust collection parts are interchangeable with plumbing, but most sizes don't match up, so when you need a specific part you have to pay the freight and get a true dust collection fitting, like this.
