## 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
