Introduction
The Ingersoll Rand 47588565001 96958111 O-Ring Module is a dedicated sealing component associated with compressor maintenance applications. The 47588565001 designation is identified with an Ingersoll Rand gearbox maintenance package, while 96958111 identifies the O-ring used within applicable service arrangements.
The 96958111 is specified as a standard SAE AS568 O-ring measuring 2-3/8 inches in inside diameter with a 0.094-inch cross-section. It is identified with FKM90 material, making it a purpose-selected sealing element rather than a generic rubber ring.
In gearbox and compressor service, a small sealing component can have a significant effect on equipment reliability. Proper sealing helps contain lubricant, protect mechanical interfaces, and reduce the risk of leakage-related maintenance interruptions. Replacing a deteriorated O-ring during planned service is therefore a straightforward but valuable maintenance measure.
For maintenance professionals, the most important consideration is application accuracy. The 96958111 should be matched with the applicable Ingersoll Rand assembly and service requirements before installation, particularly where operating fluid, temperature, and sealing conditions are critical.

Technical FAQs
1. What type of O-ring is Ingersoll Rand 96958111?
The 96958111 is identified as a standard SAE AS568 O-ring with a 2-3/8-inch inside diameter and 0.094-inch cross-section. It is also identified with FKM90 sealing material.
2. What does FKM90 indicate for the 96958111 O-ring?
FKM90 identifies the specified elastomer and hardness class associated with the sealing component. FKM materials are commonly selected for applications requiring good resistance to oils, fuels, elevated temperatures, and demanding industrial fluids.
3. What is the function of the 96958111 O-ring in a compressor assembly?
The O-ring forms a seal between compatible mating surfaces, helping prevent lubricant or other operating fluids from passing through the joint. Its effectiveness depends on correct groove design, compression, material compatibility, and installation.
4. Why is the AS568 designation important when replacing the O-ring?
The AS568 designation establishes standardized O-ring dimensional references. Matching the correct standard size helps ensure that the replacement component has the appropriate inside diameter and cross-section for the intended sealing groove.
5. Can the 96958111 be replaced with any O-ring of the same nominal size?
Not necessarily. The replacement must also meet the required material, hardness, temperature capability, chemical compatibility, and application requirements. A dimensionally similar O-ring made from an unsuitable elastomer may fail prematurely.
6. What can cause a properly sized O-ring to leak?
Leakage can result from incorrect compression, damaged sealing surfaces, contamination, twisting during installation, extrusion, aging, chemical incompatibility, or excessive temperature. The complete sealing interface should therefore be inspected when leakage occurs.
7. Should the 96958111 be lubricated before installation?
Installation practices depend on the applicable Ingersoll Rand service procedure and the fluid used in the assembly. Where lubrication is specified, the lubricant should be compatible with the O-ring material and the compressor system.
8. What should be inspected when replacing this O-ring?
The technician should inspect the groove, mating surfaces, fasteners, adjacent components, and the sealing area for scratches, burrs, contamination, deformation, or other conditions that could damage the new O-ring or prevent uniform compression.
9. What are common signs of O-ring deterioration?
Hardening, flattening, cracking, swelling, permanent deformation, surface damage, and loss of elasticity are common signs of deterioration. Visible lubricant leakage around the sealing interface can also indicate that the sealing element requires attention.
10. Why is correct part-number verification important for 96958111?
Correct verification ensures that the O-ring matches the intended compressor assembly and sealing requirements. Even when another O-ring appears dimensionally similar, differences in material and application can significantly affect service life and sealing reliability.
