The Ingersoll Rand 47690459001 / 95998076 Inlet Valve Rebuild Kit is presented here as the supplied product listing, with 47690459001 serving as the primary rebuild-kit reference.
Ingersoll Rand and industrial-parts documentation identify 47690459001 as a Kit, Inlet Valve Rebuild. A detailed shipment record further describes it as an inlet valve flapper rebuild kit for RS45-75I / RS55-75N compressors, comprising metal components such as a ring, flap assembly, and angle joint.
The inlet valve is a critical part of a rotary screw compressor's air-management system. Wear in the flapper mechanism or associated components can interfere with proper inlet control and may contribute to abnormal loading, unloading, or compressor response.
The secondary reference 95998076 requires special attention. Public listings identify it independently as an Ingersoll Rand O-ring, including an AS568 8.25-inch ID × 1/8-inch width FKM90 specification. It should therefore not be described as a confirmed supersession of 47690459001 without machine-specific documentation.
For maintenance purchasing, the safest approach is to verify the compressor model and serial number together with the complete part reference before rebuilding the inlet-valve assembly.

* The 5.05 kg figure is listed by one supplier for 47690459001, but the source does not provide a sufficiently detailed packaging breakdown to independently validate it as a physical kit weight.
For 95998076, supplier documentation specifies an AS568 8.25-inch inside diameter × 1/8-inch width FKM90 O-ring. Its separately listed net weight is 0.01 kg; this is the weight of the O-ring reference, not the 47690459001 rebuild kit.
Inlet Valve Overhaul: The 47690459001 is identified as an Ingersoll Rand Kit, Inlet Valve Rebuild for compatible compressed-air equipment. Detailed shipment documentation describes it as an inlet valve flapper rebuild kit for RS45-75I / RS55-75N compressors.
Flapper Mechanism Service: The documented kit contains metal components including a ring, flap assembly, and angle joint, allowing service of the mechanical portion of the inlet-valve assembly.
RS-Series Compressor Maintenance: The kit is particularly relevant to maintenance work on RS45–75I and RS55–75N configurations where inlet-valve wear can affect loading and unloading behavior.
Controlled Air Admission: Restoring the inlet-valve mechanism helps maintain the intended opening and closing action of the compressor intake system.
Key Strengths at a Glance
OEM Inlet-Valve Rebuild Reference: Ingersoll Rand parts catalogs identify 47690459001 specifically as an inlet-valve rebuild kit.
Flapper Rebuild Configuration: The kit is documented as an inlet-valve flapper rebuild rather than a complete replacement valve.
Metal Service Components: The documented kit comprises metal replacement components associated with the inlet-valve mechanism.
Application-Specific Service: Correct application matching is important because related Ingersoll Rand references include separate blowdown-block, modulation-block, and MPCV rebuild kits.
Technical FAQs
1. What is Ingersoll Rand 47690459001 / 95998076?
47690459001 is an Ingersoll Rand inlet valve rebuild kit. Public documentation identifies it as an inlet-valve flapper rebuild for RS45-75I / RS55-75N equipment. The 95998076 reference is separately identified as an Ingersoll Rand O-ring, so the available public evidence does not establish it as a direct supersession of 47690459001.
2. What components are included in the 47690459001 rebuild kit?
Shipment documentation describes the kit as containing a ring, flap assembly, and angle joint, with the components identified as metal parts.
3. What type of inlet valve does this kit service?
The documented description identifies it as an inlet valve flapper rebuild kit for RS45-75I / RS55-75N compressors.
4. Does 47690459001 replace the complete inlet valve?
No. It is identified as a rebuild kit, intended to service specified internal/mechanical portions of the existing inlet-valve assembly rather than automatically replacing the complete valve.
5. What is the function of the inlet-valve flapper?
The flapper forms part of the mechanism that regulates compressor inlet airflow. Its movement helps control the air admitted to the compression system during different operating states.
6. Which compressor models are documented for 47690459001?
The strongest available application record identifies RS45-75I / RS55-75N. Actual compatibility should still be confirmed using the compressor serial number and applicable parts documentation.
7. Is 95998076 the same component as 47690459001?
No reliable public source located establishes 95998076 as the same physical component or a superseding number for 47690459001. 95998076 is independently cataloged as an Ingersoll Rand O-ring, including an AS568 8.25-inch ID × 1/8-inch cross-section FKM90 specification.
8. Why is correct rebuild-kit identification important?
Inlet-valve assemblies can use different rebuild configurations. Ingersoll Rand separately lists rebuild kits for the inlet valve, blowdown block, modulation block, and MPCV, so selecting solely by general valve appearance can result in an incorrect component.
9. What should be inspected before rebuilding the inlet valve?
The technician should inspect the existing valve body, flapper mechanism, sealing surfaces, fasteners, and associated pneumatic/control components for wear, contamination, damage, or abnormal movement.
10. What information should be confirmed before ordering 47690459001?
Confirm the complete part number, compressor model, serial number, inlet-valve configuration, existing valve assembly, and applicable Ingersoll Rand parts list before ordering.
