O-rings on a weekend

In the area where I live, if you need o-rings on a weekend from a big-box or hardware store, the only choice is the Danco brand. Sure, I should plan ahead better for my surprise plumbing projects.

Those are typically labeled as '#nnn "O" RING', fits whosis, and the measured size. These '#nnn' are _not_ the SAE dash numbers.

I found it helpful to have a table of the available sizes and nomenclature, with cross-references to the SAE dash numbers. This can be found in the Danco catalog, available as a PDF from the Danco website, on sheets 132-134. Look at the bottom of the homepage for 'Download Catalog'.
