Ridgid 37920 Pipe Thread Die 3/4 in 4 Pc

This set provides four high-speed steel replacement dies for cutting right-hand NPT threads on 3/4-inch stainless steel pipe. It is designed for plumbers and pipefitters who need reliable threading performance on corrosion-resistant materials using compatible handheld equipment.

Capacity and headroom: 14 threads per inch

The dies cut standard 14 TPI NPT threads on 3/4-inch stainless steel pipe with high-speed steel construction for wear resistance. They are not intended for larger diameters, different thread pitches, or materials outside the specified stainless steel application.

Replaces worn dies in Ridgid 0-R, 00-R, 11-R, 12-R.

This four-piece set directly replaces damaged or dull dies in the listed Ridgid die heads for handheld manual and power threaders. The upgrade is worth it when existing dies no longer produce clean threads on stainless steel or when switching to a dedicated stainless steel die set for the first time.

  • Works with Ridgid 0-R, 00-R, 11-R, 12-R, 30A and 31A die heads

Questions about this item

Will the 37920 dies work with my existing Ridgid 12-R die head?

Yes, the dies are compatible with Ridgid die heads including the 12-R, 11-R, 00-R, 0-R, 30A and 31A models for handheld manual and power threaders.

How can I confirm the dies are cutting the correct 14 threads per inch NPT profile?

After threading, check the thread pitch with a thread gauge; it should measure 14 threads per inch and show a clean right-hand NPT profile on stainless steel pipe.

Does the 37920 set include the die head or just the four high-speed steel dies?

The set contains four replacement dies only; a compatible Ridgid die head such as the 12-R or 30A must be purchased separately if you do not already own one.
