Product Overview

The Ingersoll Rand 24509192 85576692 Hose is a hydraulic hose assembly associated with the oil-cooling circuit of selected Ingersoll Rand rotary screw air compressors. The 85576692 reference identifies a hose measuring 1.50 inches in nominal size and 24 inches in length, with straight ORFS and 90-degree ORFS end connections.

In an oil-injected screw compressor, the oil circuit carries lubricant through components involved in lubrication, sealing, and heat removal. The hose provides a flexible connection between the cooler block and the associated oil passage, allowing fluid to move through the circuit without relying entirely on rigid pipework.

This hose is associated with the NG R-Series 30–37 kW compressor platform, including applicable R30 and R37 configurations. Its end-fitting arrangement matters because the hose must connect correctly to the mating adapters while following the intended route through the cooling assembly. A hose with a similar diameter but different end orientation may not fit the original installation.

During cooler maintenance, technicians may inspect this hose for oil seepage around the crimped ends, abrasion along the outer cover, or deterioration caused by repeated heating and cooling. Replacing a damaged line helps restore the integrity of the oil circuit, but the condition of the connecting adapters and sealing interfaces should also be checked.

The part numbers 24509192 and 85576692 are retained as supplied in the product title. Before replacement, verify the complete reference against the installed compressor configuration and the original hose arrangement.

Technical Specifications

Product Features

• Oil-circuit fluid transfer: Carries fluid between the designated cooler and oil-circuit connections.
• Flexible hose construction: Accommodates the routing required within the compressor assembly.
• Defined end orientation: Combines a straight ORFS connection with a 90-degree ORFS connection.
• Specified hose length: The 24-inch catalog length helps identify the intended replacement configuration.
• Dedicated part identification: The 85576692 reference distinguishes this hose from other lines in the compressor assembly.
• Maintenance replacement: Allows a damaged hose to be renewed without automatically replacing the cooler or adjoining components.
• Assembly-specific fitment: Requires the correct hose size, connection geometry, and routing to maintain the intended installation.

Working Principle

The 85576692 hose acts as a fluid passage within the compressor’s oil-cooling arrangement. During operation, circulating oil moves through the connected passages and cooling components. The hose links the designated connections while accommodating the physical layout of the assembly.

A simplified arrangement is:

Compressor Oil Circuit → Cooler Block Connection → 85576692 Hose → Mating Oil-Circuit Connection

This is a functional illustration rather than a complete hydraulic schematic. The actual flow direction and connection sequence depend on the compressor’s installed configuration.

The hose wall contains the fluid, while the hose construction supports the pressure and temperature conditions encountered in service. Crimped end fittings secure the connections, and the ORFS interfaces provide sealing when correctly matched with their mating components.

For example, when a compressor cooler is removed for servicing, the connected hose may need to be disconnected to gain access to the assembly. During this work, the technician should check the hose ends for oil residue, inspect the crimp areas for deterioration, and examine the adapters for damaged sealing faces.

A hose can also fail prematurely if it is twisted during installation, bent beyond its permitted radius, or routed against a hot or moving component. These problems may occur even when the replacement has the correct nominal size and length. Correct orientation and clearance are therefore essential parts of the installation.

The hose itself does not regulate oil temperature or generate fluid flow. Those functions depend on the compressor’s oil-circulation and cooling equipment.

Role in the Compressor Oil-Cooling System

The 85576692 connects designated points in the compressor’s oil-cooling circuit. Its flexible construction and end-fitting arrangement allow the oil line to follow the intended route between the adjoining components.

Industrial Applications

Installation and Maintenance

1. Verify the complete part reference: Confirm 24509192 and 85576692 against the compressor’s parts list and installed hose identification.
2. Identify the compressor configuration: Check the model and serial number, particularly for equipment within the R30–R37 range.
3. Inspect the original connection arrangement: Record which end connects to each port and note the orientation of the straight and 90-degree fittings.
4. Shut down and isolate the compressor: Follow the equipment’s approved isolation procedure before working on the oil circuit.
5. Allow the system to cool: Hot oil and nearby components can cause burns. Wait until the assembly is safe to handle.
6. Release stored pressure: Follow the prescribed procedure to establish a safe pressure condition before disconnecting the hose.
7. Examine the existing hose: Look for cracking, abrasion, bulging, exposed reinforcement, oil seepage, or damage near the crimped ends.
8. Check the mating fittings: Inspect the ORFS sealing faces, adapters, threads, and surrounding connections for damage or contamination.
9. Confirm replacement compatibility: Verify the hose size, length, fitting orientation, connection type, and required operating specifications before installation.
10. Install without twisting the hose: Align the end fittings with their designated ports and follow the specified tightening procedure. Do not force the hose into position.
11. Check routing and leakage: Confirm that the hose has adequate clearance from hot surfaces and moving components. Restore the system according to the approved procedure and inspect for leakage.
12. Record the service work: Document the installed part number, observed hose condition, any damaged fittings, and the results of the post-maintenance inspection.

• Helps maintain circuit integrity when correctly matched, routed, and installed.

Technical FAQs

Which connections are used on the 85576692 hose?

The catalog description identifies a 1.50-inch hose with a straight ORFS connection at one end and a 90-degree ORFS connection at the other. Confirm the actual fitting orientation against the installed assembly before replacement.

Which compressor models are associated with this hose?

The 85576692 is associated with selected NG R-Series 30–37 kW compressors, including applicable R30 and R37 variants. Confirm the machine’s model, serial number, and cooler configuration before selecting the replacement.

Why should the ORFS fittings be inspected when replacing the hose?

The fittings must mate correctly with the hose ends to maintain a sealed connection. Damaged sealing faces, contamination, or incorrect assembly can cause oil leakage even when the replacement hose is correct.

Can another 1.50-inch hose be used instead of the 85576692?

Not solely on the basis of nominal size. The replacement must also match the required length, end connections, fitting orientation, pressure and temperature ratings, fluid compatibility, and routing requirements.
