Product Overview
The Ingersoll Rand 47642697001 95023388 O-Ring is a sealing component used in compatible Ingersoll Rand compressor assemblies. It forms a seal at a mating interface where two components must remain mechanically joined while preventing lubricant or other fluids from passing through the joint.
Unlike a shaft seal, which operates around a rotating shaft, an O-ring is normally used at a stationary interface. Its sealing performance depends on the condition of the groove, mating surfaces, O-ring material, and correct compression after assembly.
In compressor maintenance, this type of O-ring can be relevant when servicing the shaft sealing area or other connected mechanical components. If an O-ring is removed during disassembly, replacing it rather than reinstalling a deformed or compressed ring helps maintain the intended sealing condition.

Product Features
- Used as a sealing component in compatible Ingersoll Rand compressor assemblies.
- Provides sealing at a stationary mating interface.
- Helps prevent lubricant or fluid leakage through component joints.
- Compact geometry allows installation in a dedicated sealing groove.
- Suitable for compressor maintenance and replacement work.
- Requires clean and undamaged mating surfaces for proper sealing.
- Should be evaluated together with the associated groove and mating components.
Working Principle
The O-ring sits inside a machined groove between two mating components. Once the components are assembled, the ring is compressed against the surrounding surfaces. This deformation creates the contact needed to close the leakage path around the joint.
In a compressor assembly, pressure and lubricant can act on the sealed interface during operation. The O-ring maintains contact with the groove and mating surface so that fluid does not migrate through the joint.
Correct installation is important. Twisting, cutting, pinching, contamination, incorrect groove seating, or damage to the mating surfaces can create a leakage path even when the O-ring itself is new. During service, the O-ring should therefore be inspected as part of the complete sealing interface rather than as an isolated component.

Installation and Maintenance
- Confirm the replacement part
Verify the 47642697001 assembly reference and 95023388 part number before installation. - Inspect the existing O-ring
Look for flattening, cuts, cracks, hardening, deformation, or other signs of deterioration. - Inspect the sealing groove
Make sure the groove is clean and free from burrs, corrosion, deposits, or mechanical damage. - Check the mating surfaces
Inspect both contact surfaces for scratches, dents, contamination, or other defects that could create a leakage path. - Clean the installation area
Remove old lubricant, dirt, sealing residue, and foreign material before installing the replacement O-ring. - Verify the O-ring dimensions
Confirm the supplied part against the required ID × OD × Cross-Section: 142.875 × 149.225 × 3.175 mm before assembly. - Prevent twisting during installation
Position the O-ring evenly in its groove and avoid twisting, stretching, or pinching it during assembly. - Check adjacent components
When servicing the shaft sealing area, inspect the related shaft seal, motor shaft sleeve, housing, and other sealing components. - Avoid damaged tools
Do not use sharp or rough tools that could cut or scratch the O-ring or sealing groove. - Check component alignment
Assemble the mating components evenly so that the O-ring receives uniform compression around the interface. - Inspect for leakage after startup
After reassembly, monitor the serviced area for lubricant leakage or other signs of an incomplete seal. - Record the replacement
Document the part number and maintenance condition to support future compressor service and troubleshooting.

Technical FAQs
What is the function of the Ingersoll Rand 47642697001 95023388 O-Ring?
It seals a stationary mating interface within a compatible compressor assembly. The compressed O-ring closes the potential leakage path between the surrounding components.
What do ID, OD, and Cross-Section mean for this O-ring?
ID refers to the inside diameter, OD refers to the outside diameter, and Cross-Section refers to the thickness of the O-ring material. For this part, the supplied dimensions are 142.875 × 149.225 × 3.175 mm.
Why can an O-ring leak even when it has just been replaced?
Leakage can result from incorrect seating, twisting, pinching, contamination, groove damage, damaged mating surfaces, or incorrect compression. The surrounding mechanical interface should be inspected whenever a new O-ring does not seal correctly.
Should the 95023388 O-Ring be replaced during shaft seal maintenance?
If the O-ring is part of the interface being disassembled, replacement is generally appropriate because removal can leave the existing ring deformed or damaged. The associated shaft seal, motor shaft sleeve, groove, and mating surfaces should also be inspected during the same service operation.
