The Vevor ratchet pipe threader kit is designed for efficient manual pipe threading across a wide range of common BSPT pipe sizes. It includes 7 dies for plumbing installation and repair work on copper, aluminum, galvanized, and iron pipes. Hardened 9CrSi dies help produce clean, accurate, burr-free threads with strong wear resistance. A long non-slip handle improves grip and torque while reducing hand fatigue during use. The included carrying case keeps the set organized and portable for jobsite or workshop use.
