RIDGID National Pipe Straight Mechanical Thread

RIDGID National Pipe Straight Mechanical (NPSM) Thread Dies for Manual Threaders are precision-engineered cutting tools designed to produce accurate, uniform external straight pipe threads. Manufactured for professional plumbing, mechanical contracting, industrial maintenance, and commercial piping applications, RIDGID NPSM threading dies provide dependable cutting performance, excellent durability, and consistent thread quality. These replacement pipe dies are designed for use with compatible RIDGID manual ratchet threaders and pipe threading die heads.

RIDGID NPSM Straight Pipe Threading Dies

RIDGID National Pipe Straight Mechanical threading dies produce parallel pipe threads conforming to applicable ASME B1.20.1 specifications. Unlike National Pipe Taper (NPT) threads, NPSM threads maintain a constant diameter throughout their threaded length rather than incorporating a 1:16 taper.

NPSM connections are commonly used in mechanical pipe assemblies, fittings, couplings, and applications requiring straight-thread engagement. Unlike tapered NPT connections, NPSM threads generally require a separate sealing method when a pressure-tight connection is necessary.

RIDGID NPSM Manual Threader Compatibility

RIDGID offers NPSM replacement threading dies for compatible 00-R, 11-R, and 12-R manual ratchet threading systems. Available pipe sizes range from 1/8" through 2", depending on the specific die head.
