"not for use with drip tubing??"

This item at Lowe's:

says "not for use with drip tubing". Any idea why not? Seems pretty basic, not sure why it would be a problem?

Probably the barb is slightly over or undersized compared to drip tubing size.

Rainbird got back to me, saying:
Yes — there is a technical reason that fitting is labeled “not for use with drip tubing.” It’s not a marketing restriction; it’s about how drip tubing seals and behaves under pressure.

Hmm. I'm still going to take some drip tubing to the store and see, and for $0.99 may try it if it seems to fit. There isn't going to be THAT much pressure--this will be downstream of the cutoff.
