A find at TSC

[texbaylea]

I was there yesterday to get a couple of standard Pioneer 1/2" NPTF male QD halves. Saw some with 3/4" ORB female threads that were marked that they would couple against residual pressure. I had never seen or heard of this before for this type of QD. If they had had 1/2" NPTF I would have bought them to try.

Is this something new?
