I don't know why no one advertises this fact, it was wayyyy harder to find an adapter to turn my regular 1/2" shower outlet into a regular 3/4" hose outlet.  BAM! this adapter works PERFECT.  I put it on with teflon tape but I don't know if it needed it.  It's solidly made and the threads on both sides matched up perfectly.  Want to attach a garden hose to your shower, get this adapter and it's all smoooooth sailing!
