I'm learning already

you will have to buy an adaptor though to use your 1/2 tubing, pity, 1/2 barbs would have been easier
but as this block is possibly catering more to the mainstream and even OEMs, as others have pointed out, 3/8 barbs are indeed easier I suppose

How can that be? Using smaller barbs slows down the flow. How can that be a good thing?
