Ferguson or Home Depot may sell pipes 1 inch outer diameter. Is this tolerable or needs exact .92 ?

Where am I?

In Maker Pipe Connect DIY Community you can ask and answer questions and share your experience with others!

You can use the connectors with 1" outer diameter pipes as long as you remove the friction band, but it is a very tight fit. I recommend taking a connector with you to pick up your pipes that way you can test the fit before buying the pipe. 

I compared the diameter of 1” EMT to that of 1” pvc conduit. The 1” EMT is slightly smaller than other pipes I’ve used in my 1” connectors (see my post on these other pipe comparisons). This small difference could help after the bands are removed as Jake commented.
