Perfect for Blichmann 1/2 in. ball valves and Fermenator conical fermenters! This isn't the cheap 1/2 in. nipple available from the big chain hardware store down the street. Blichmann has created this stainless steel nipple out of high quality 304 steel, and has included a 7/8 in. hex fitting in the center so that the nipple can be safely secured in your brewing setup with a wrench. The 1/2 in. NPT standard threading works with a myriad of brewing equipment, including Blichmann QuickConnectors!
