It is an good kit but the safety adapter does NOT fit 1/2 inch - I had to buy another BrassCraft 1/2" kit with a different safety adapter in conjunction with this universal kit to have a complete kit as the safety adapter is too small.  As another reviewer mentioned kind of silly to be so stingy on the pipe sealant that you feel yourself potentially needing a bit more. (given how cheap a giant tube is)
