## Questions & Answers

**Q: Inside diamater of the 8"?**
A: Tube or coupling described as 8-In has an inside diameter of 8-In.

**Q: Will this work for a 2.5” shop vac hose?**
A: Should work

**Q: Inside diameter of 1 1/4**
A: A 1-1/4” rubber sleeve will fit a 1-1/4 PVC pipe!    A 1-1/4” PVC pipe has an OD of 1.6” and the sleeve has an ID of 1.6 “ so it fits perfectly over the pipe.  It works that way with all the sizes - the PVC’s OD is ALWAYS the same as the sleeves ID.  PVC pipe is sold based on it’s ID and it’s OD is always more.  Fittings, connectors and sleeves are always sold by the size pipe they are meant to fit (typically slid over) so will have a larger ID than the pipes announced size.  Ex: 1-1/2” PVC is 1-1/2” ID but 1.9” OD.  You would need to buy a 1-1/2” rubber sleeve  (with an ID of 1.9) to fit over the PVC tube!   Don’t complicate it any more than the manufacturers already have!   Pipe is sold by their ID and fittings are sold by the pipe size that they fit.

**Q: inside diameter of 4-inch?**
A: The inside diameter is like 4.3 made to fit a 4 inch pipe

*by C***Y on 25 August 2020*

Item I have in hand advertised and labelled 1 1/2 inch, but actual id = almost 1 7/8 inch, and od = 2 3/8 inch. Supply Giant must have a giant ruler! Update 8/31/20: I subsequently bought a 11/2 inch coupler from Home Depot thinking it would be right coming from a trusted home repair specialized vendor, and it came and while from a different manufacturer it also was 1 7/8 inch id! I’m no plumber, maybe it can or is meant to be tightened down to 1 1/2 inch? I do not know, I did not try, since with the same 1 1/2 inch coupler Home Depot order, just in case at this point what with shipping costs etc. to factor in, I also bought a 1 1/4 inch coupler (actual id = 1.5 inches) and it does work for me, I am using it for a 1 1/2 inch under sink Snappy Trap install. So, I now reserve judgement since I may just be ignorant of coupler sizing specs, change to 3 star, and suggest you may need to try more than one size, which is usual for me and plumbing anyway! 9/4/2020 update: I changed to five star since I now think the sizing must be intended for PVC pipes with id 1 1/2 inch, and since pvc pipes have thick walls you would need the coupler labelled for 1.5 inch pvc pipe to have id 1 7/8 inch. In that case the manufacturer cannot avoid confusion except by providing a lengthy analysis that will result in confusion anyway. My non-professional conclusion is that apparently these are pvc couplers that when labelled 1.5 inch have id 1 7/8 inch, and those labelled 1.25 inch have id 1.5 inch. They work for other than pvc pipe, but getting the right size is tricky.
