3/4 in NPT alloy-steel die set

This Ridgid 37830 set contains four alloy-steel dies cut to a 3/4 in NPT right-hand thread form with 14 threads per inch. They are made for threading aluminium or steel pipe and fit Ridgid handheld manual and power threaders using 0-R, 00-R, 11-R, 12-R, 30A or 31A die heads. The dies are supplied new and ready for workshop use.

Professional pipe-fitters and maintenance crews

The set suits plumbers and pipe-fitters who cut 3/4 in NPT threads on aluminium or steel pipe with compatible Ridgid threaders. It will not serve anyone needing a different thread standard, a different pipe diameter, left-hand threads or dies for powered threaders that use another die-head pattern.

14 threads-per-inch NPT right-hand pitch

The single specification that decides fit is the 14 threads-per-inch NPT right-hand pitch. If the job calls for that exact thread form on 3/4 in pipe, these dies match; if the required pitch or thread standard differs, the set cannot be used.

Questions about this item

How do I install the 37830 dies into a compatible Ridgid die head?

Snap the four dies into the matching slots of a 0-R, 00-R, 11-R, 12-R, 30A or 31A die head so the cutting edges face the pipe rotation direction.

What maintenance will the 37830 alloy steel dies need?

Brush chips from the 14 threads-per-inch cutting edges after each use and apply light oil to prevent rust.

What limit appears first when threading 3/4 in pipe continuously?

The 14 threads-per-inch pitch removes more material per turn, so the dies heat up and dull faster on long runs.
