The Ingersoll Rand 95439006 O-Ring is a sealing component associated with Ingersoll Rand Centac centrifugal compressor equipment. Parts listings identify this reference in the P140 parts category and describe it as an O-ring used in the compressor assembly.
In a centrifugal compressor, sealing components are required at interfaces where housings, covers, and other stationary parts meet. The O-ring forms a sealing barrier between mating surfaces, helping prevent air or operating fluid from escaping through the joint during normal operation.
The effectiveness of the seal depends on the groove geometry, compression, material compatibility, and operating conditions at the installation point. Pressure fluctuations, temperature changes, and prolonged exposure to operating media can affect the sealing material over time.
For maintenance teams, correct part identification is important when several O-rings appear in the same compressor parts list. Components that look similar may have different sealing profiles or serve different joints. Confirming the part number and installation location before dismantling the assembly helps avoid incorrect replacement and recurring leakage problems.

The 95439006 O-ring seals through compression between two mating surfaces. When fitted into the designated groove, the ring deforms against the surrounding surfaces, closing the clearance through which air or another operating medium could escape.
A typical sealing arrangement follows this sequence:
Compressor Housing or Cover → Machined Groove → O-Ring → Mating Surface
The groove controls the ring’s position and compression. Insufficient compression can prevent the seal from making adequate contact with the mating surfaces, while excessive compression may damage the material during assembly.
During operation, pressure and temperature changes place demands on the sealing interface. The O-ring material must remain compatible with the operating medium and retain suitable elasticity under the specified conditions. Material deterioration, incorrect sizing, or damaged mating surfaces can cause leakage even when the joint has been assembled correctly.
During servicing, inspect the removed ring for flattening, cuts, cracks, hardening, and other signs of deterioration. Check the groove for contamination, scratches, corrosion, and damage that could affect the seal’s contact with the mating surface.
The replacement must match the specified application. Verify the part number and sealing profile against the compressor parts documentation before installation, and use only an approved lubricant or assembly aid where the procedure permits it.
The 95439006 O-ring serves as a stationary sealing element at its designated installation point. It supports the integrity of the joint while the compressor’s other components perform their mechanical and fluid-handling functions.

Parts listings identify 95439006 in the P140 parts category. Confirm the complete compressor model and installation location against the applicable parts list before selecting the replacement.
The sealing profile determines how the ring sits in its groove and compresses against the mating surfaces. An incorrect profile may prevent proper sealing or cause damage during assembly.
Verify the part number and specification first. Then inspect the groove for debris, deformation, or damage, and confirm that the replacement matches the intended application. Do not force a ring into a groove that appears incompatible.
Inspect the ring, groove, and mating surfaces for wear, contamination, and damage. Confirm the assembly sequence and fastening requirements, then evaluate the operating conditions at the joint. Repeated leakage may indicate a damaged sealing surface or incorrect part selection.
