1/4 Threading Die 1-15439 Good Quality Waterjet Parts

The 1/4 Threading Die 1-15439 is a precision-machined threading tool specifically designed for cutting accurate 1/4-inch high-pressure threads on stainless-steel tubing used in ultra-high-pressure (UHP) waterjet systems. Manufactured from hardened tool steel, this die delivers clean, consistent threads capable of withstanding working pressures up to 60,000 psi (4,137 bar) — ensuring safe and leak-free connections in critical waterjet assemblies.

The 1-15439 Threading Die is engineered to meet OEM specifications for compatibility with KMT, FLOW, BFT, and WSI waterjet systems. It produces precise cone-and-thread connections, maintaining the correct geometry and surface finish required for high-pressure sealing integrity. Its robust construction and sharp cutting edges make it ideal for repeated use in both maintenance workshops and production environments.

This threading die is an essential tool for fabricating, repairing, or customizing high-pressure tubing, allowing technicians to create exact OEM-quality threads for connectors, elbows, and fittings — ensuring long-lasting, high-performance waterjet connections.
