RIDGID National Pipe Straight Mechanical Thread 12-R Die Head

RIDGID National Pipe Straight Mechanical (NPSM) Thread 12-R Die Heads are professional-grade pipe threading accessories designed to produce accurate, consistent external straight pipe threads. Engineered for precision, durability, and dependable performance, these heavy-duty RIDGID 12-R die heads are ideal for professional plumbers, mechanical contractors, industrial maintenance technicians, and pipe fabrication specialists. Designed for use with the RIDGID Model 12-R Manual Ratchet Threader, these interchangeable die heads provide reliable threading performance for demanding commercial and industrial piping applications.

RIDGID 12-R NPSM Straight Pipe Threading Performance

RIDGID 12-R NPSM die heads are designed to produce straight, parallel external pipe threads conforming to applicable ASME B1.20.1 specifications. Unlike National Pipe Taper (NPT) threads, which feature a 1:16 taper, NPSM threads maintain a constant diameter throughout their threaded length.

NPSM threads feature a 60-degree thread angle and are primarily designed for mechanical connections rather than pressure-tight sealing through thread interference.

RIDGID 12-R NPSM Die Head Features and Specifications

• Thread Standard: National Pipe Straight Mechanical (NPSM), ASME B1.20.1.

• Thread Direction: Right Hand (RH), depending on die configuration.

• Thread Profile: 60-degree angle with parallel threads.

• Available Sizes: Selected nominal pipe diameters and corresponding threads per inch (TPI).

• Die Head Design: Heavy-duty exposed manual ratchet threading.

• Threader Compatibility: RIDGID Model 12-R Manual Ratchet Threader.

• Cutting Dies: Replaceable dies matched to the specified thread size.

• Durable Construction: Engineered for demanding industrial applications.

• Manual Operation: Requires no electrical power.

RIDGID 12-R NPSM Die Head Applications

RIDGID 12-R NPSM die heads are ideal for mechanical pipe assemblies, industrial machinery, equipment maintenance, plumbing components, and pipe fabrication applications requiring straight-thread connections. Unlike tapered NPT connections, NPSM joints generally require a separate sealing method when pressure-tight performance is necessary.
