English Translation of Title:
High-Pressure Fitting for Water Jet Cutting Machine Parts – Actual: 765.19431, Nominal: 800.20320, Model No. 10138709-Actual-in-765-19431-Nominal-in-800-20320.1170.3-1

(Note: The numbers "765.19431" and "800.20320" are likely internal reference codes or proprietary sizing designations rather than standard dimensional values.)

Introduction, Application, Features, and Maintenance:

This component is a high‑pressure fitting designed for water jet cutting systems. Its model number includes both an actual reference (765.19431) and a nominal reference (800.20320), indicating it is a precision-machined connector used to join high‑pressure lines, valves, or other hydraulic components in the machine’s fluid circuit.

Application:
Used in the high‑pressure plumbing of water jet cutting machines to connect tubing, hoses, pumps, attenuators, valves, or cutting head assemblies. It ensures a leak‑free interface between system components and may serve as an adapter, coupling, or transition piece depending on its specific geometry.

Features:

• Rated for extreme pressures up to 6,000 bar (87,000 psi), typical of water jet systems.

• Manufactured from high‑strength, corrosion‑resistant material (e.g., stainless steel or high‑grade alloy) to withstand abrasive water jet media.

• Precision‑machined sealing surfaces (e.g., cone, O‑ring groove, or flat face) provide reliable leak protection.

• Dimensional references (actual/nominal) indicate fine-tuned manufacturing tolerances for proper fit and function.

• Compact design suitable for dense machine layouts.

Maintenance:

• Regularly inspect the fitting for signs of erosion, pitting, thread damage, or cracking.

• Check all connection points for high‑pressure leakage during machine operation.

• Replace the fitting immediately if any surface wear, deformation, or leakage is observed.

• Use compatible seals, washers, or thread sealants as required by the connection type.

• Follow specified torque values when tightening mating components.

• Clean threads and sealing surfaces thoroughly before reinstallation.
