POWERTEC 70136 4" to 2-1/2" Cone Reducer, Dust Collection Fittings for Dust Collection Hose to Hose Connection

I'm just finishing my new shop and needed these to finishing installing my dust collection. They are good quality and they do the job. Fit is good with other product lines. Thanks

Works and fits great. Used this product to connect a Vevor dust separator to my 2 1/2 wet dry vac. Value for the money

It works. Seems solid and well made. The design works.

Fits both 4" and 2.5" flexible hoses for dust collection well. Maybe a bit over priced IMHO.

Fits shop vac hose well. Good quality.

This fits perfectly into my 2-1/4" preformed hose end to use my dust collector on my bandsaw. It's held up well, removing it many times.

Works as described. However, the sizes listed are HOSE sizes. So, this will allow you to connect a 4" hose (i.e., from your dust collector) to a 2.5" hose (i.e., to your miter saw or router table). As others have found, the outlet on your saw or inlet on the dust collector is the same size as the larger side of the cone, so you cannot connect this directly to your machine. I admit I have made the similar mistake and had to return a few items. However, that was my mistake. I have used this item several times, and it works just fine. The hoses are a bit snug, but I suppose that is by design, possibly so you can connect hoses without using a hose clamp. However, I used clamps on both side just to be certain. I was able to connect my miter saw and my router table to my dust collector without any issues. I would recommend using as short of a 2.5" hose as possible to help maximize the airflow, if connecting this to a 4" dust collector intake.

I knocked a star off for this company's insistence on putting their company sticker in the worst location on every part they make. In this case, that placement is smack dab in the mouth of the part. Ordinarily, no big deal. But apparently they've teamed up with 3M and NASA to design an adhesive that will not come off with ANY solvent. Alcohol, Goo Gone, mineral spirits, NOTHING WILL REMOVE this stickiness. Now I get to enjoy a nice sawdust spot there for the duration of it's life. This is mild in comparison to their sticker placement on their 4" to 2 1/2" reducer. In this case, these geniuses put the sizable-thickness sticker directly on the male end to be mated to the hard plastic coupler.

Good quality, as expected.

Very happy really good size well made

Be aware that dust collection sizes are not universal. These are meant to fit malleable dust collection hoses - not necessarily hard plastic fittings of the same size. My table saw has a 4" port and this product has a 4" port - guess what? They don't fit as they're exactly the same. Easy fix with epoxy and black duct tape. However the 2.5" port fit perfectly with my 2.5" Ridgid shop vac hose with no adjustment whatsoever.

Lo compré para usarlo con mi nuevo extractor pero no le quedó, este acople es de mayor a menor, solo consideren eso antes de hacer su compra para que no se equivoquen como yo :/
