I was assembling a little adapter to make tying a garden hose into an

They were both marked "outdoor use only".

Why? It doesn't make any difference to me because they were going outside,
but it made me curious.

Perhaps the garden hose barb is not an approved fitting for indoor
plumbing. Pvc is ok for potable cold water so that's not the reason.

No barbs involved. the non-hose end was a plain end that took cement.
I am not sure, but is the standard hose thread what is used on a washing
machine?
We only use cold water for the washing machine but the little label on both
pieces said outdoors only. Nothing about temperature or potable water.
That's why I raised the question. I can't think of why this application of
PVC would be any different than for other pieces. There are unions, for
example, that are essentially compression fit.
