## Questions & Answers

**Q: Can I use this to connect my dryer hose and bathroom exhaust fan to share one outlet through the wall? I ask because someone said it is not advised.**
A: Unless you have one-way valves on both exhausts prior to the Y junction, I definately wouldn't do it. Also, one way valves take some air volume to open them, so the bath fan would have to overcome that, plus if both the dryer fan (powerful) and bath fan (less powerful) are operating at the same time, the dryer fan might force the bath fan valve shut. Good luck!

**Q: For a bathroom exhaust fan, isn’t it better for the flow to be coupled male into female on the way out?**
A: you are connecting the aluminum ducting to this from your fan. this is for connecting 2 attic ducts. I connected attic exhaust fan to bathroom duct to vent my hot attic outside.

**Q: Can this be used in the attic as a combiner for venting bathrooms? What metal is it? Thanks**
A: I don't see why not (combiner). Looks like galvanized,  ferrous sheet metal.

**Q: Is this safe for electric clothes dryer and Is there a cap for one end?**
A: It is aluminum so it is safe for the dryer vent tubing. no caps.  I used it for a attic fan to vent 2 tubes.  Plus wrapped all connections with aluminum duct tape. (not the regular duct tape).

*by R***. on Reviewed in the United States on 2 June 2024*

It appears to be good quality! I ran 2 bathroom fans into this y pipe and then out of one exterior vent. It’s preforms nice and helps me keep the smell and noise down in the bathroom with out having to run 2 separate ducts and vents

*by N***U on Reviewed in the United States on 17 July 2020*

Professional handyman here. I know quality materials when I see them. This thing is the highest quality duct piece I've come across!Heavier-gauge metal than I'm used to seeing (no, I'm not talking about what you'll find at the Orange or the Blue Behemoths, that stuff is so thin it's not even worth consideration). Solidly-built joints -- good spot-welds along the Y joints, tight seams that are both crimped AND stitch-welded. The double clamp-retention shoulders are better than most. I can't get it to flex, much less crush.The thing that really sets this apart from the rest is the mastic spread across all seams and joints. What other fitting have you found that comes pre-sealed with mastic?!? That's usually something I have to do on site. And it's not all globby or sloppy. It's even painted the same color as the fitting! WHO DOES THAT??!!??Yeah, okay, so it's a duct fitting. Nothing to get excited about. I get it. But it's rare to come across quality like this any more.
