Product Name: Clamping Nut (4-inch) / Retaining Nut (Part No. 1-13484)

Description:
This component is a clamping nut, also known as a retaining nut or nozzle nut, designed for the cutting head assembly of a high-pressure waterjet cutting system. The "4-inch" designation refers to the standard size of the mating thread or the specific cutting head model. It is a precision-machined, high-strength stainless steel component that serves to secure the focusing tube (mixing tube) and other internal components within the cutting head body, while maintaining precise coaxial alignment for jet coherence.

Applications:

• Secures the mixing tube (focusing tube) within the cutting head assembly

• Retains internal components in proper alignment for optimal cutting performance

• Suitable for abrasive waterjet cutting systems operating at 60,000 PSI and above

• Compatible with standard 4-inch cutting head configurations

Features:

• High-Strength Stainless Steel Construction: Provides corrosion resistance and structural integrity under extreme pressure cycling

• Precision-Machined Threads: Ensures smooth engagement with the cutting head body for consistent clamping force

• 4-Inch Design: Standard configuration for specific cutting head models

• Wrench Flats or Knurling: May feature flats for tool tightening or a textured surface for hand operation (depending on design)

Maintenance:

• Regular Inspection: Periodically check the clamping nut for signs of thread wear, galling, corrosion, or deformation

• Torque Compliance: Tighten to the torque value specified in the equipment service manual to ensure proper sealing and prevent component damage

• Thread Lubrication: Apply high-pressure thread lubricant or anti-seize compound to threads during reassembly to prevent galling

• Replacement Criteria: Replace immediately if threads are damaged, cracks are visible, or deformation is detected

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before loosening or removing the nut
