Product Name: Hydraulic Hose Assembly (.75 x 41.0) – Part No. 05071105

Description:
This component is a hydraulic hose assembly, specifically a 3/4 inch (.75) inner diameter hose with a length of 41.0 inches. It is designed for use in the low-pressure hydraulic circuit of waterjet cutting systems. The hose assembly is manufactured from wire- or textile-reinforced synthetic rubber, capable of withstanding the extreme pulsation, vibration, and pressure requirements of waterjet intensifier operation. It is listed as Item 8 in Table 12-35 of the Redundant Kit 72155777 (Quantity: 2), confirming its role as a critical fluid conduit for the intensifier pump‘s hydraulic system.

Applications:

• Transmits hydraulic fluid under pressure between the main pump, redundant pump, and the intensifier cylinder in the Redundant Kit 72155777 .

• Serves as a flexible connector for hydraulic lines in waterjet power units, accommodating machine motion and dampening vibration.

• Compatible with KMT, AccuStream, and other standard waterjet hydraulic systems.

Features:

• Hydraulic Hose Construction: Typically features a synthetic rubber inner tube, steel wire braid or spiral reinforcement for high pressure, and a durable rubber outer cover resistant to abrasion and hydraulic fluids.

• Size Designation: .75 indicates a 3/4 inch nominal inner diameter, a standard size for medium-flow hydraulic circuits in waterjet systems.

• Length: 41.0 inches, providing sufficient length for proper routing within the hydraulic power unit.

• Pre-assembled: Supplied as a complete hose assembly with pre-crimped, corrosion-resistant steel fittings (likely JIC or ORB type) on both ends, ready for installation.

• Critical Redundancy Component: Essential for applications requiring a backup hydraulic supply. In the Redundant Kit, two of these assemblies connect the primary and redundant systems.

Maintenance:

• Visual Inspection: Before each use, inspect the hose assembly for signs of leakage, cover damage (cuts, abrasion, bulging, blistering), kinking, or twisted fittings .

• Leak Detection: Pay particular attention to any relief holes in the fittings; if fluid weeps from these holes, the fitting seal has failed and the assembly must be replaced immediately .

• Torque Compliance: When installing, tighten the end fittings to the specific torque value in the equipment service manual. Use two wrenches—one to hold the fitting and one to tighten the nut—to prevent twisting the hose.

• Routing Check: Ensure the hose is not routed near sharp edges, hot surfaces (e.g., heat exchanger), or moving parts. Use clamps or nylon ties to secure the hose and prevent chafing.

• Replacement Criteria: Replace the hose assembly immediately if any of the following are detected: exposed reinforcing wires, cracked or damaged fittings, severe cover deterioration, kinks, or if it has exceeded the manufacturer‘s recommended service life . Do not attempt to patch or repair a high-pressure hydraulic hose.

• Full Depressurization (Critical): Before any maintenance, fully depressurize the hydraulic system, shut down the high-pressure water pump, and follow lockout/tagout procedures. High-pressure fluid injection injuries are severe and require immediate medical attention.
