Product Overview
The Ingersoll Rand 47588446001 95070272 O-Ring is a replacement sealing component used in compatible Ingersoll Rand compressor assemblies. Its primary function is to create a seal between mating surfaces, helping prevent oil or air leakage at the connection where the ring is installed.
O-rings are commonly used throughout rotary screw compressor systems, including valve assemblies, fluid connections, and housings where components must maintain a seal under pressure, temperature changes, and repeated operating cycles. The ring sits in a designated groove and compresses against the mating surface when the assembly is tightened, forming a seal around the joint.
The 95070272 part number is listed as an Ingersoll Rand O-ring, with a catalog description identifying it as a 2 × 2-1/8 × 1/16 inch O-ring. It is also associated with the Standard 033 designation in some parts listings. The exact installation location and material specification should be verified for the particular compressor assembly rather than inferred from the part number alone.
During compressor maintenance, a worn or damaged O-ring can contribute to oil seepage, pressure leakage, or loss of sealing at a valve or fitting. Common causes include compression set, surface damage, contamination, incorrect installation, and exposure to operating conditions outside the seal material’s intended range.
When replacing this component, the groove dimensions, mating surfaces, and required seal material all matter. A ring that appears similar may not provide the correct fit or resistance to the oil and temperature conditions encountered in the installed assembly.

Product Features

- Compact sealing component: Fits into a specified groove or sealing interface within the assembly.
- Compressor service application: Can be used when the corresponding O-ring is identified for the installed equipment.
- Replacement during overhaul: Allows a worn or damaged seal to be renewed without automatically replacing the surrounding component.
- Part-specific identification: The 95070272 reference helps distinguish the ring from other O-rings used throughout the compressor.
- Seal-interface maintenance: Supports inspection and servicing of joints exposed to oil, pressure, and operating-temperature changes.
Working Principle
The 95070272 O-ring seals a joint by deforming slightly when compressed between two mating surfaces. The resulting contact pressure restricts the path through which oil, air, or another compatible fluid could escape.
A typical sealing arrangement follows this principle:
Groove or Seal Seat → O-Ring → Mating Surface → Sealed Connection
In a compressor valve assembly, for example, an O-ring may seal the interface between a housing and a removable component. When correctly installed, the ring fills the designed sealing space and maintains contact as the assembly experiences normal operating pressure and temperature changes.
Over time, an O-ring can lose its ability to recover after compression. Hardening, swelling, cuts, twisting, or extrusion can compromise the seal. A small defect may produce visible oil seepage, while leakage at a pressure-control component can also affect the system’s operating behavior.
Replacement involves more than fitting a new ring. The technician must check the groove and mating surfaces for scratches, corrosion, and contamination. The replacement must match the required dimensions and material, and it must be installed without twisting or cutting the sealing surface. Lubrication during assembly should follow the applicable procedure and use a compatible lubricant.
Role in the Compressor Sealing System
The O-ring provides sealing at a specific interface within the compressor assembly. Its exact function depends on the component in which it is installed.

Installation and Maintenance
- Verify the part number: Confirm 47588446001 and 95070272 against the equipment’s parts documentation before installation.
- Identify the sealing location: Determine which valve, housing, or connection uses the O-ring in the installed compressor configuration.
- Isolate the equipment: Follow the approved shutdown procedure and ensure the relevant circuit is in a safe condition before disassembly.
- Release stored pressure: Depressurize the affected air or oil circuit as required before opening the joint.
- Remove the old ring carefully: Avoid scratching the groove or mating surface with sharp tools during removal.
- Inspect the removed seal: Look for flattening, cuts, hardening, swelling, twisting, or other evidence of deterioration.
- Clean the seal groove: Remove oil residue and debris using a method compatible with the surrounding materials.
- Check the mating surfaces: Inspect for scratches, corrosion, burrs, and other defects that could create a leakage path.
- Confirm replacement suitability: Verify the required dimensions and material for the actual application rather than relying on visual similarity alone.
- Install without twisting: Seat the ring evenly in the groove and avoid stretching, pinching, or cutting it during assembly.
- Reassemble and test: Follow the specified assembly procedure, restore the circuit safely, and inspect the joint for leakage under the applicable test conditions.
- Record the maintenance work: Document the part reference, installation location, observed seal condition, and any leakage findings.

Technical FAQs
What should be verified before selecting the 95070272 O-ring?
Confirm the part number, installed component, groove dimensions, and required seal material. The catalog size description alone does not establish compatibility with every compressor assembly.
Can a damaged O-ring cause oil leakage around a valve housing?
Yes. A cut, hardened, flattened, or incorrectly seated O-ring can allow oil to escape through the joint. Damaged mating surfaces or loose fasteners can cause similar symptoms and should also be inspected.
Is the 95070272 suitable for both static and dynamic sealing?
The part’s actual duty depends on the assembly in which it is installed. Confirm whether the seal is used in a stationary joint or a moving interface before assessing material and installation requirements.
Should an O-ring be reused after a valve assembly has been dismantled?
Replacement is generally appropriate when the service procedure calls for a new seal or when the removed ring shows deformation or damage. Reusing a compressed or damaged O-ring can increase the risk of leakage after reassembly.
