Product Name: Replacement Threading Die (Part No. 400118-1)

Description:
This component is a replacement threading die, a precision cutting tool used to cut external threads on high-pressure (HP) stainless steel tubing for waterjet cutting systems. The die is used in a manual or machine threading tool holder and is designed to cut threads that match the specifications of standard waterjet high-pressure fittings (e.g., gland nuts). Using a dedicated die ensures the threads are cut cleanly, concentric with the tube axis, and free of the defects that can cause galling and high-pressure leaks.

Applications:

• Cutting new threads on HP tubing during the fabrication of custom-length high-pressure lines

• Replacing damaged threads on existing HP tubes

• Re-sharpening or replacing the die when it becomes dull after extensive use

Features:

• Precision Ground: Manufactured to exacting tolerances for cutting threads that meet OEM specifications

• High-Speed Steel (HSS) Construction: Made from durable HSS or similarly hardened steel for longevity in machining stainless steel

• Specific Thread Profile: Designed to cut the unique thread form and pitch required by waterjet high-pressure fittings (refer to the equipment service manual for the specific thread size, e.g., 9/16-18 UNF)

• Wear Item: Dies are consumable tools; a dull die produces rough or undersized threads that will not seal properly

Maintenance:

• Replace When Dull: Using a dull die can work-harden the tubing and cause galling. If the die requires excessive force, produces a rough finish, or leaves visible tears on the threads, it must be replaced immediately

• Lubrication: Always use heavy-duty cutting oil or the specific coning/threading oil (e.g., 400120-1) when cutting threads. Lubrication is critical for preventing galling and extending die life

• Cleaning: After use, clean the die thoroughly with a solvent to remove metal chips and cutting oil. This prevents rust and keeps the cutting edges sharp

• Storage: Store the die in a clean, dry environment or protective case to prevent edge damage and corrosion
