Review: Works just as you'd expect. - 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. Review: Effective solution to a problem - So, let me lead with saying I have no idea what this was actually intended for by the manufacturer. All I know is I needed a 4 inch "nominal" diameter object to connect from the intake of a 1997 F250 7.3L to a NAPA 6637 filter because I leaned too hard on the stock intake box and broke the plastic (thereby ruining that whole "seal" thing that supposed to happen to prevent dust from getting sucked into the engine.) I visited the hardware store first and came up with a few mediocre solutions with PVC fittings that would... work... then saw this. For less money, this solves the problem by actually fitting (OD of the truck's fittings was about 4 1/4, ID about 3 7/8 - this fits in the ID with a little bit of give that you can clamp down on with a 4" hose clamp on either end). Again, don't know what this thing was SUPPOSED to be fore, but it sure does do a great job as a cheap intake pipe for my truck :-) ## Features - INCLUDES: 4 in. to 2-1/2 in.

All I know is I needed a 4 inch "nominal" diameter object to connect from the intake of a 1997 F250 7.3L to a NAPA 6637 filter because I leaned too hard on the stock intake box and broke the plastic (thereby ruining that whole "seal" thing that supposed to happen to prevent dust from getting sucked into the engine.)

I chose to use a 45 in this position to help maintain velocity and reduce the chance of plugging.
