JIC Coupling for Water Jet Cutting Machine Parts – 75 x 75, Model No. 20436321-Coupling-JIC-75-x-75.1250.3-1

Introduction, Application, Features, and Maintenance:

This component is a JIC (Joint Industry Council) coupling designed for water jet cutting systems. It features 75 mm nominal size connections on both ends, providing a secure, leak‑free straight‑through connection between two JIC‑compatible high‑pressure lines or components.

Application:
Used to connect high‑pressure lines, fittings, or valves in water jet cutting machines. Typical installations include joining pump outlets to attenuators, connecting valve assemblies, or linking cutting head supply lines where a JIC‑to‑JIC connection is required.

Features:

• Rated for extreme pressures common in water jet cutting, up to 6,000 bar (87,000 psi).

• Both ends feature 75 mm JIC connections for straight‑through flow.

• Precision‑machined flared sealing surfaces ensure leak‑free operation.

• Manufactured from high‑strength, corrosion‑resistant material suitable for abrasive water jet media.

• Compact design minimizes space requirements and reduces potential leak points.

• Easy to install and disconnect for maintenance or system reconfiguration.

Maintenance:

• Regularly inspect the coupling body, threads, and flared sealing surfaces for signs of erosion, cracking, or thread damage.

• Check both connection ends for high‑pressure leakage during machine operation.

• Replace immediately if any leakage, surface pitting, or thread damage is detected.

• Use compatible seals or lubricants as recommended.

• Follow specified torque values when tightening both connection ends.

• Inspect the flare surface for scratches or damage that could compromise sealing.
