The 1/2 have a split in them 3/8 don't. I was thinking about closing the gap up but I don't think that will work & look good.I wasn't able to find out if the 1/2" ones I have would work with the 3/8" valves. If you want them anyway tho, I can send them your way snail mail. They don't weigh much at all, so no cost. Btw, they are bare steel, not chrome.
