What type of threads or profile are you repairing?

INCH / METRIC / PIPE
SQUARE, GROOVE, SNAP-RING
S154 – If the groove, thread, or slot is greater than 0.047″ wide. See below!
S218 – If the groove, thread or slot is greater than 0.090″ wide. See below!
382 & 154 are the winners. Both repair down to 28 TPI (threads per inch) [0.8 metric].
See tech spec’s below for which is better for you.
752, 754, & 218 is the clear choices for your needs. These will repair down to 13 TPI (threads per inch) [2.0 metric].
For detailed spec’s about which of the 3 is optimal for your specific application see below!
LARGE THREAD DIAMETER (2+ inches, ID/OD)
382 if the threads look FINE (down to 28 TPI [0.8 metric]).
218 if they look COARSE (down to 13 TPI [2.0 metric]).
These larger wheels are considered Heavy Duty and will provide more life and better performance for these bigger size diameters.
STILL NOT SURE?
Threads are measure by the inch. Here’s a quick way to tell what you have, count the number of threads inside 1 inch on a ruler and subtract 1. That’s the TPI of the thread!
All of our tools will fix any pitch, but some of our models are better spec’d for the finer ones. This illustration should help: All inch, metric, and pipe threads have 60 degree angle, but finer threads are shallower than coarse. We made the 382 & 154 with a tighter nose to get down into the smaller root.
