Milwaukee 3/8"-18 NPT Pipe Taper Tap

Milwaukee 3/8"-18 NPT Taper Tap

The 49-57-5292 Milwaukee 3/8"-18 NPT Taper Tap is a precision threading tool designed for creating and repairing tapered pipe threads, helping ensure tight, leak-resistant connections in a wide range of metal applications. Built from high carbon steel and finished with a black oxide coating, it offers durability and corrosion resistance for repeated use. The tapered design allows for a gradual, controlled thread start—because pipe threads should seal properly the first time, not after a second attempt and a little extra persuasion.
