When you’re repairing hydraulic lines or replacing pipe fittings on your tractor, sometimes the threads get damaged or stripped out. This 1/8 inch NPT hex die lets you rethread those fittings or create new NPT threads on pipe and rod stock. It’s one of those handy tools that saves the day when you’re trying to get a tight seal on hydraulic connections or air lines.
What You’re Getting
- Standard 1/8 inch NPT (National Pipe Thread) with 27 threads per inch spacing
- Hex design fits standard die handles and tap wrenches for easy turning
- High-quality steel construction that stays sharp through repeated use
- Creates proper tapered threads that seal tight with pipe compound or Teflon tape
Built for Real Farm Work
NPT threads are everywhere on farm equipment – from hydraulic fittings and air lines to gauge connections and small fuel lines. This die handles the smaller 1/8 inch size that’s common on pressure switches, temperature sensors, and auxiliary hydraulic connections. Whether you’re working on a compact utility tractor or a big row-crop machine, you’ll run into these threads.
Made to Last
This die is made from hardened steel that holds its edge even when cutting through tough hydraulic fittings or galvanized pipe. The hex shape distributes turning force evenly, so you get clean, accurate threads without the die slipping or binding up on you.
Good to Know
Start your threads straight and turn slowly – NPT threads are tapered, so they get tighter as you go. Use cutting oil or even a drop of hydraulic fluid to make threading easier and get a cleaner finish. Remember that NPT threads seal on the tapered surfaces, not just the thread peaks, so don’t overtighten and risk cracking the fitting.
