02C200 - Walter 1-1/4 Inch NPT Carbon Steel Threading Tap

Precision Threading for Industrial Maintenance

The Walter 02C200 1-1/4" NPT Carbon Pipe Tap is a specialized tool engineered to meet the rigorous demands of industrial maintenance, repair, and operations (MRO). Crafted from premium carbon alloy tool steel, this tap is designed to deliver a balance of hardness and toughness, ensuring it can withstand the torque required for cutting large diameter pipe threads without succumbing to premature breakage. The material composition is specifically selected to provide longevity when working with mild steels and non-ferrous metals, making it an essential component of any comprehensive tool crib.

Accuracy is paramount in piping systems where leak-proof seals are required. This Walter tap features precision-ground threads that conform strictly to National Pipe Taper (NPT) standards. This ensures that every thread cut or restored provides the necessary interference fit for a secure, pressure-tight seal. Whether utilized for fabricating new connections in a fluid transfer system or for the critical task of restoring damaged threads on expensive fittings, this tool delivers consistent, reliable results. The manufacturing process includes a hardening and tempering cycle that optimizes the grain structure of the steel, enhancing wear resistance and edge retention over repeated uses.

Designed with the user in mind, the tap incorporates a standard square drive shank, allowing for secure engagement with tap wrenches and preventing slippage during high-force manual threading. The flute geometry is engineered to effectively evacuate chips, reducing friction and heat buildup which can otherwise degrade thread quality. For facility managers and maintenance professionals, the Walter 02C200 represents a dependable solution for keeping piping infrastructure operational and efficient.

Technical Specifications and Application

This tool is rated for use on a variety of materials common in industrial environments, including aluminum, brass, copper, and mild steel. It is particularly effective for "chasing" or cleaning existing threads that have been contaminated with rust, paint, or weld spatter, restoring them to their original functional state. While optimized for maintenance tasks, its durable construction also supports the cutting of new threads in compatible materials, providing versatility across different job requirements.
