I'm looking for a stainless steel T or Y splitter with 1/2" barbs on all three ends. Basically I want to take the output hose from my pump and split it into two hoses so I can fill two carboys at once. Can't find them anywhere!
If you are using 1/2" silicon hoses, you could do this with copper. Just use a tee with short stubs put into each end. The hoses slip right on without barbs and stay put pretty well. You'd have to solder the copper, but this would make what you need.
