Review: I got this earlier than expected an it works great. It's well made and durable and fits perfectly. However I should ass make sure you read ALL of the description as I have seen some negative reviews for Bellends who gave negative reviews about not fitting and explaining in detail how they tried everything to make it work EXCEPT follow the directions. you need to by the rubber flex cuff to attach to your machines. As this is a solie plastic and so is the out port on your equipment I don't know how people can't understand that there would be no way to put a hose clamp (or duct tape on this) and tighten it. So I would say disregard any reviews complaining about fit and more on to others because it fitas fine and works great and I would highly recommend this product. BTW one last though make sure you know your inside diameter of the hose you are reducing to this doesn't fit many shop vacs but fits my grizzly table saw's overhead dust collection hose (it has a 4" port under the blade and a 2.5" hose coming off the blade guard) and this is because many shop vacs are NOT 2.5". Just measure your hose or check your operators manual for specs and order the correct one as they do offer several different and even universal ones
Review: Good quality, as expected.

## Questions & Answers

**Q: Which hose adapter reducer should I get that will connect onto a 4" diameter blast gate outlet then onto or in a 2 1/2" diameter port fitting tblesaw?**
A: Not this adapter, unless you went to HD or Lowes and purchased a 4" thin wall PVC straight connector to convert the blast gate to female. Look at WoodRiver 2-1/2" O.D. Hose to 4" O.D. Quick-Connect Dust Collection Fitting, it appears to be more toward what you are looking for, with a female 4" and will do 2.5" or 2.25" hose connections.

**Q: Can I use it to reduce a 4" pvc pipe (water pipe) to a 2-1/2" dust collector hose?**
A: you would have to measure the inside and out Dia.of your pipes.and then check what this product dimensions.

**Q: Will this connect directly to 4" abs pipe?**
A: No, you will need a 4”coupler.

**Q: I have a Jet bandsaw and the dust comes from a 4" outside dim hole I need to cover and to attach it to a 2 1/4 outside dim vac hose.  Will this work?**
A: It looks like the small end is 2 1/4 ID and 2 3/8 OD. The larger end is 3 3/4 ID and 3 7/8 OD. These are tape measurements, not calipers
