Pipe Thread Die Set 37940

This Ridgid 00-R die set contains four high-speed stainless steel replacement dies for manual pipe threaders. It cuts right-hand NPT threads at 11 1/2 threads per inch for nominal 2-inch pipe. The set is designed for use with Ridgid 00-R, 11-R, 12-R and 0-R ratchet threader die heads as well as 30A and 31A 3-way pipe threaders. It suits plumbers and maintenance crews who need to re-thread or repair stainless steel piping on site.

Replaces Worn Dies for 2-Inch NPT Work

The set replaces dull or damaged dies in compatible Ridgid threader heads so you can restore clean, accurate threads on 2-inch stainless steel pipe. The jump is worth it when existing dies produce rough threads, require excessive force or fail to hold tolerance on NPT joints. It is not for users threading other pipe sizes, different thread standards or materials not rated for high-speed stainless steel dies.

Fits Ridgid Ratchet and 3-Way Threaders

The dies install directly into Ridgid 00-R, 11-R, 12-R and 0-R ratchet die heads and 30A and 31A 3-way threaders, requiring no adapter or modification. They free up the threader for continued use on 2-inch stainless steel pipe without sending the tool out for regrinding. The set does not support left-hand threads, other thread pitches or pipe diameters outside the stated nominal size.

Questions about this item

Which die heads accept the 37940 die set?

The dies fit RIDGID 00-R, 11-R, 12-R and 0-R ratchet threader die heads, plus 30A and 31A three-way pipe threaders.

How do you seat the dies in the head without damaging the threads?

Align each die with its numbered slot, press evenly until the retaining clip clicks, then rotate the head by hand to confirm smooth engagement before applying load.

When should the high-speed stainless-steel dies be replaced?

Replace the set when threads show galling, pitch errors on NPT 11 1/2 cuts, or when the right-hand cutting edges no longer produce clean roots on 2 in nominal pipe.
