Product Overview
The Ingersoll Rand 47642697001 39454558 Gasket is a flat sealing component used in compatible Ingersoll Rand compressor assemblies. It is installed between mating surfaces to close small surface irregularities and prevent lubricant, air, or other fluids from escaping through the joint.
Unlike an O-ring, which sits inside a dedicated groove, a gasket normally covers a defined sealing face between two stationary components. Its sealing performance depends on correct positioning, surface condition, compression, and the integrity of the surrounding hardware.
During compressor maintenance, the gasket may need to be replaced whenever the associated joint is opened. Reusing a compressed or damaged gasket can introduce a leakage path even when the mating components themselves remain serviceable.

Product Features
- Used as a flat sealing component in compatible Ingersoll Rand compressor assemblies.
- Provides sealing between stationary mating surfaces.
- Helps prevent lubricant, air, or fluid leakage through the assembled joint.
- Covers a defined sealing face rather than relying on a circular sealing groove.
- Suitable for compressor repair and maintenance work.
- Requires clean, flat, and undamaged mating surfaces for proper sealing.
- Should be inspected together with the associated bolts, sealing faces, and adjacent components.
Working Principle
The gasket is compressed between two mating components when the assembly is tightened. Its material conforms to minor surface irregularities and fills the potential leakage path between the two sealing faces.
In a screw compressor, pressure differences and lubricant circulation can place continuous demands on stationary sealing joints. A correctly installed gasket maintains contact across the mating surfaces and helps keep the fluid contained within the intended passage or housing.
Gasket leakage is not always caused by the gasket itself. Uneven tightening, damaged sealing faces, contamination, incorrect positioning, or distortion of the mating components can also prevent proper sealing. For this reason, gasket replacement should include an inspection of the complete joint.
Role in a Screw Compressor Mechanical Architecture
| System Element | Function |
|---|---|
| Compressor Housing | Provides the stationary structure for mechanical components |

| Gasket | Seals the stationary interface between mating components |
| O-Rings | Provide sealing at applicable component interfaces |
| Shaft Seal | Controls leakage around the rotating shaft |
| Motor Shaft Sleeve | Provides the designated surface for the shaft sealing arrangement |
| Lubrication System | Circulates lubricant through the compressor |
| Compressor Airend | Performs the primary compression process |
| Fasteners | Apply the required clamping force across the sealed joint |
| Compressor Control System | Monitors and manages compressor operation |

Installation and Maintenance
- Confirm the replacement part
Verify the 47642697001 assembly reference and 39454558 gasket part number against the applicable compressor documentation. - Inspect the old gasket
Look for compression marks, tears, cracks, deformation, burning, or other signs of deterioration. - Clean the mating surfaces
Remove old gasket material, lubricant residue, dirt, and foreign particles before installing the replacement. - Inspect the sealing faces
Check both mating surfaces for scratches, dents, corrosion, distortion, or other defects that could affect sealing. - Verify gasket condition
Make sure the replacement gasket is flat and undamaged before positioning it on the sealing face. - Check gasket orientation and position
Align the gasket correctly with the mating components and make sure all required openings are properly positioned. - Avoid unnecessary bending
Handle the gasket carefully during installation to prevent creasing, tearing, or permanent deformation. - Inspect related O-rings and seals
If the same assembly contains O-rings or shaft seals, inspect them while the joint is open. - Check fasteners
Inspect the associated bolts, studs, and other fastening hardware for damage or abnormal condition. - Apply even clamping force
Tighten the joint according to the applicable compressor maintenance procedure so the gasket receives uniform compression. - Check for leakage after reassembly
Run the compressor under normal conditions and inspect the serviced joint for lubricant, air, or other fluid leakage. - Record the maintenance work
Document the gasket replacement and any observed surface or fastening issues for future compressor service.

Technical FAQs
What is the function of the Ingersoll Rand 47642697001 39454558 Gasket?
The gasket seals the joint between two stationary mating surfaces. When compressed during assembly, it fills minor surface irregularities and helps prevent air, lubricant, or fluid from passing through the joint.
Why should the 39454558 Gasket normally be replaced after disassembly?
Once compressed, a gasket may not return to its original sealing condition. Reusing it can result in uneven compression or leakage, particularly when the joint has been opened for compressor maintenance.
What should be checked if a new gasket still leaks?
Inspect the mating surfaces for scratches, corrosion, distortion, or contamination. Also check gasket positioning and the clamping condition of the fasteners. Uneven tightening can prevent uniform gasket compression.
Can this gasket be replaced without checking the surrounding seals?
The surrounding sealing components should also be inspected whenever the assembly is open. O-rings, shaft seals, and other sealing interfaces may have related wear or damage that can produce leakage in the same area.
