Product Overview

The Ingersoll Rand 47553887001 85575173 Hydraulic 1 X 34 Hose is a hydraulic hose assembly used in compatible Ingersoll Rand compressor equipment. It connects hydraulic circuit components through a combination of straight and angled fittings, allowing fluid to pass between connection points while accommodating the routing constraints of the machine.

In large industrial compressors, hydraulic hose assemblies must withstand operating pressure, vibration, temperature changes, and movement transmitted through the surrounding structure. A damaged hose or poorly seated fitting can lead to fluid leakage, pressure loss, and unplanned equipment downtime. Selecting the correct replacement therefore requires attention to the connection arrangement as well as the hose specification.

The 85575173 configuration is identified as a 1-inch hydraulic hose with a straight ORFS connection at one end and a 90-degree ORFS elbow at the other. The straight fitting provides a direct connection to its mating port, while the angled fitting changes the hose’s exit direction. This arrangement can help accommodate equipment layouts where a straight connection would create unnecessary routing difficulties.

When replacing this hose, maintenance personnel should verify the complete part number, fitting orientation, sealing surfaces, and hydraulic circuit requirements. Similar-looking hoses may differ in connection geometry, pressure capability, or intended application. Matching the original assembly is essential to avoid installation stress and compatibility problems.

Technical Specifications

Product Features

• Straight and angled fittings: Combines a straight ORFS connection with a 90-degree ORFS elbow for a defined routing arrangement.
• One-inch nominal hose size: Identifies the specified hose configuration for replacement selection.
• Hydraulic circuit compatibility: Connects designated components when the hose specifications match the operating requirements.
• ORFS sealing interfaces: Uses O-ring face seal connections intended to provide sealing at compatible mating ports.
• Assembly-specific identification: The 85575173 part number helps distinguish this hose from other hydraulic hose variants.
• Flexible routing: The hose body accommodates the required path between connected components, subject to its permitted bend radius.
• Maintenance replacement: Allows the original hose assembly to be replaced without changing the surrounding circuit configuration unnecessarily.

Working Principle

The 85575173 hose carries hydraulic fluid between two connection points in the circuit for which it is specified. Its hose body forms the fluid passage, while the end fittings provide the mechanical connections and sealing interfaces.

At the straight end, the ORFS fitting connects directly to a compatible mating port. At the opposite end, the 90-degree ORFS elbow allows the hose to change direction near the connection point. This difference in fitting orientation helps determine how the hose can be routed through the machine.

A typical connection arrangement follows this path:

Hydraulic Circuit Component → Straight ORFS Connection → Hose 85575173 → 90° ORFS Elbow → Connected Component

During operation, hydraulic fluid moves through the hose according to the pressure differential and flow requirements of the associated circuit. The hose must maintain its internal passage while resisting the pressure, temperature, and mechanical conditions specified for the application.

The ORFS connections rely on compatible mating faces and correctly positioned sealing elements. Contamination, damaged sealing surfaces, incorrect assembly, or misalignment can create leakage paths. Similarly, forcing the hose into a tight bend or twisting it during installation can introduce unnecessary stress into the assembly.

The hose does not independently regulate hydraulic pressure or control fluid distribution. Those functions depend on the surrounding hydraulic components, such as pumps, valves, and actuators, where fitted. The hose’s role is to maintain the required fluid connection between them.

Role in a Compressor Hydraulic System

The 85575173 hose forms part of the fluid connection between components in its assigned hydraulic circuit. Its precise position and function depend on the compressor configuration, so the original parts breakdown should be used to establish the connected components.

Hydraulic Source or Manifold → ORFS Connection → 85575173 Hose → ORFS Elbow Connection → Receiving Component

Correct installation preserves the intended routing and connection geometry. The exact circuit function and operating limits must be confirmed for the equipment in which the hose is installed.

Industrial Applications

The hose should only be used where its connection design, fluid compatibility, pressure rating, and temperature limits meet the requirements of the installation.

Installation and Maintenance

1. Verify the part number: Confirm that 47553887001 and 85575173 match the hose specified for the compressor assembly.
2. Identify the hydraulic circuit: Establish the hose’s function and identify both connected components before removing the original assembly.
3. Isolate the equipment: Shut down the compressor, isolate the relevant energy sources, and release stored hydraulic pressure according to the approved service procedure.
4. Record fitting orientation: Note the position of the straight ORFS fitting and the 90-degree elbow before disconnecting the hose.
5. Inspect the hose body: Check for abrasion, cuts, cracking, bulging, crushing, or other signs of deterioration.
6. Examine the ORFS interfaces: Inspect the mating faces and sealing areas for scratches, contamination, deformation, or damaged sealing elements.
7. Clean the connection points: Remove dirt and residue using an approved cleaning method to prevent contaminants from entering the hydraulic circuit.
8. Confirm replacement compatibility: Check the hose part number, fitting configuration, fluid requirements, and operating specifications before installation.
9. Route the hose correctly: Avoid sharp bends, excessive tension, twisting, and contact with hot surfaces or moving machinery.
10. Secure the fittings: Follow the specified assembly procedure and tightening requirements for the ORFS connections.
11. Inspect under operating conditions: After completing the approved test procedure, check the connections for leakage and verify that the hose remains clear of surrounding components.
12. Document maintenance findings: Record the installed part number, inspection results, and any signs of contamination, fitting damage, or premature hose wear.

Never search for a hydraulic leak by placing a hand near a pressurized connection. High-pressure fluid can penetrate the skin and cause serious injury. Depressurize the system before adjusting fittings or removing the hose.

Compatible System Components

Technical FAQs

What does the 1 X 34 designation mean for the 85575173 hose?

The designation identifies a nominal one-inch hose configuration with a specified length of 34 inches. The complete assembly must also be checked for its end-fitting arrangement and operating requirements.

Are both ends of the 85575173 hose straight ORFS connections?

No. The identified configuration has a straight ORFS fitting at one end and a 90-degree ORFS elbow at the other. This orientation must match the original installation.

Can a JIC hose be used as a direct replacement for the 85575173?

Not automatically. JIC and ORFS connections use different sealing arrangements. Even when the nominal hose size and routing length are similar, the fitting type and mating ports must be compatible with the intended system.

What can cause premature wear on this hydraulic hose?

Common installation-related causes include excessive bending, twisting, abrasion against nearby components, heat exposure, and poorly aligned fittings. Operating outside the hose’s specified pressure or temperature limits can also shorten its service life.
