Ridgid 141 4 Inch Geared Threader NPT

Thread large-diameter heavy-wall pipes with unyielding power and precision using the industry-standard RIDGID 141 Geared Pipe Threader (Cat # 36620). Built for heavy mechanical contracting, fire protection installation, and industrial piping crews, this rugged tool handles 2-1/2", 3", 3-1/2", and 4" nominal pipe sizes using a single set of high-speed dies. Its simple cam-adjustment mechanism lets operators quickly select pipe size and seamlessly switch between tapered NPT and straight threads. Equipped with an enclosed gear train packed in heavy-duty lubricant, the 141 protects moving parts from metal cuttings and field grit while its built-in drive clutch prevents binding when driven manually or powered by a RIDGID 300 Power Drive.

Key Features:

• Large Capacity Range: Threads 2-1/2", 3", 3-1/2", and 4" iron, steel, and galvanized pipe sizes.

• Simple Cam Adjustment: Easily locks into distinct pipe diameters and adjusts for tapered or straight threading configurations.
