Ridgid 38050 Dies12R 1/4" NPT HS LH

The Ridgid 38050 Dies set engages with a compatible head assembly to cut external 1/4-inch NPT high-speed left-hand threads onto pipe ends as controlled rotational force and pressure are applied through a threading machine. Cutting teeth progressively shape and remove metal from the pipe surface while maintaining alignment and consistent pitch to form standardized left-hand thread patterns throughout the operation. This component is typically placed in compatible 12R heads for use in piping threading machines during plumbing installation, fabrication tasks, or maintenance work in workshops, manufacturing, or field service conditions.
