Product Details
Understanding NPT Threads
NPT (National Pipe Taper) threads are used for joining pipes in many industries. The tapered design creates a compressive, leak-resistant seal when wrapped with thread sealant. Always cut with the correct die and cutting oil for clean, strong threads.
How to Use a 12R Ratchet Threader
Attach the die head securely, align the ratchet handle, and rotate clockwise while applying even pressure. Use cutting oil to reduce friction and protect the die. Reverse the ratchet to back out.
Replacement Dies and Where to Find Them
Look for RIDGID 37412 or equivalent 1-1/2-inch NPT dies that fit the 37410 head. Genuine RIDGID dies are recommended for best compatibility and thread quality.

Solid die head
I've used this on my 12R threader for a month. The NPT threads come out even. The ratchet action is smooth. It's a genuine RIDGID so I trust it. The die head is heavy and solid. Good investment.

Fits my father's tools
My father was a plumber and left me his tools. I needed a new die head for his 12R. This fits perfectly. The threading is smooth. I've made several joints and they all fit. It's a quality tool that honors his legacy.
