Ridgid RDD34 Npt Alloy Pipe Dies 3/4 Inch 12R

Product Description

The RIDGID RDD34 is a set of alloy pipe dies machined to cut 3/4 inch NPT (National Pipe Taper) threads on ferrous and non-ferrous pipe. Designed for use with compatible RIDGID 12R die heads, these dies deliver clean, accurate threads that meet NPT taper and pitch standards. Plumbers, pipefitters, and mechanical contractors use this die set in the field and in the shop when threading pipe for gas, water, or steam distribution systems. The alloy construction maintains cutting edge integrity through extended production threading runs.

These dies are intended for threading 3/4 inch pipe stock in residential and commercial plumbing and mechanical piping systems. Typical applications include threaded assembly of black iron gas pipe, galvanized water supply lines, and similar schedule-rated pipe. The 12R die head platform is commonly found on RIDGID handheld and stand-mounted threading machines used by licensed plumbing and pipefitting contractors.

Installation Notes

Die sets should be installed and removed by a qualified plumber or pipefitter familiar with the threading machine manufacturer's procedures. Ensure the threading machine is fully powered down and de-energized before changing dies. Use the appropriate threading oil during operation to extend die life and produce clean thread form. Verify die seating and head locking mechanism engagement before resuming threading operations.
