2 in NPT Thread Die Set

The Ridgid 37850 provides four alloy steel dies for cutting right-hand NPT threads on 2 in pipe. It fits Ridgid handheld die heads including the 0-R, 00-R, 11-R, 12-R, 30A and 31A models. The set works with both manual and power threaders for pipe installation or repair.

Plumbers cutting 2 in NPT threads

This set suits professionals who need to thread aluminum or steel pipe at 11 1/2 threads per inch using compatible Ridgid equipment. It is not for users who require dies for different pipe diameters, left-hand threads, or thread standards such as BSPT. Buyers without a matching Ridgid die head cannot use these dies.

Four dies for 11 1/2 TPI NPT

The decisive specification is the 11 1/2 threads per inch NPT pitch matched to 2 in pipe. Confirm your die head part number is listed in the compatibility range before purchase.
