The Ingersoll Rand 47690462001 / 95987988 MPCV Rebuild Kit is a service-oriented listing for maintenance of compressor valve and sealing components.
The primary reference 47690462001 is documented as an MPCV Rebuild Kit, with multiple parts records specifying the RS45–75I/N application. The kit is intended for rebuilding the minimum pressure check valve using serviceable internal components rather than automatically replacing the complete valve assembly.
The supplied secondary reference 95987988 is an Ingersoll Rand O-ring. Its application is not limited to the MPCV: an Ingersoll Rand XFE/EPE/HPE manual identifies it as an O-ring used at the first-stage gear spacer. For this product listing, the two supplied references are treated as one listing as requested, but the exact function of 95987988 should be confirmed against the compressor's model and serial-number-specific parts documentation.
An MPCV plays an important role in an oil-injected rotary screw compressor because minimum internal pressure supports proper oil circulation and separator-system operation. When internal valve components become worn, rebuilding the assembly can be a practical maintenance approach.
For professional service teams, correct identification is particularly important because similar-looking check-valve and sealing components can have different dimensions, pressure ratings, and application ranges.

The published 5.05-lb value is associated with the 47690462001 listing, but the supplier does not clearly distinguish product weight from packaged/shipping weight; it should therefore be treated as a reference value rather than a guaranteed net weight.
47703539001 is specifically identified as an MPCV installation kit, while 47690461001, 47690460001, and 47690459001 are related Ingersoll Rand inlet-valve rebuild references used in compressor service work.

Ingersoll Rand Minimum Pressure / Check Valve
Where It Excels in Industrial Use
Minimum Pressure Check Valve Service: The supplied 47690462001 / 95987988 references are treated as one product listing. 47690462001 is identified as an Ingersoll Rand MPCV rebuild kit, specifically associated with RS45–75I/N compressors.
Compressor Pressure Management: The minimum pressure check valve helps maintain the required internal compressor pressure while controlling the transition of compressed air toward the discharge system.
Scheduled Valve Overhaul: The rebuild-kit format is suited to preventive maintenance and corrective service where the valve body remains serviceable but internal components require renewal.
Sealing-System Maintenance: 95987988 is separately documented as an Ingersoll Rand O-ring. In an Ingersoll Rand XFE/EPE/HPE manual, it is specified as an O-ring for the first-stage gear spacer, showing that this reference is an application-specific sealing component rather than the MPCV itself.
Key Strengths at a Glance
Dedicated MPCV Rebuild Design: 47690462001 is consistently identified as a Kit, MPCV Rebuild, with application information for RS45–75I/N configurations.
Defined Service Function: The kit is intended to renew serviceable components of the minimum pressure check valve rather than automatically replacing the complete valve assembly.
Mechanical Valve Components: Import documentation describes the kit as containing valve-related components including springs, washers, rings, and a metal component.
OEM-Referenced Sealing Part: 95987988 is available as an Ingersoll Rand O-ring and has been used across multiple rotary screw compressor applications.
Technical FAQs
1. What is Ingersoll Rand 47690462001 / 95987988?
The supplied references are treated as one product listing. 47690462001 is an Ingersoll Rand MPCV rebuild kit, while 95987988 is an Ingersoll Rand O-ring reference associated with compressor sealing applications.
2. What does MPCV mean?
MPCV means Minimum Pressure Check Valve.
3. What is the purpose of the MPCV?
The MPCV helps maintain minimum internal pressure in an oil-injected rotary screw compressor and regulates the flow of compressed air from the separator system toward the discharge circuit.
4. Which compressors are associated with 47690462001?
Available parts records identify 47690462001 as an MPCV rebuild kit for RS45–75I/N compressor configurations.
5. What type of components are included in the rebuild kit?
Trade documentation describes the kit as a repair set containing springs, washers, rings, and a metal component. Exact contents should be confirmed against the current OEM bill of materials.
6. What is 95987988?
95987988 is an Ingersoll Rand O-ring. An Ingersoll Rand XFE/EPE/HPE manual lists two 95987988 O-rings for the first-stage gear spacer.
7. Is 95987988 itself an MPCV component?
Available documentation does not establish 95987988 as an exclusive MPCV component. It is documented as an O-ring used in other Ingersoll Rand compressor assemblies as well, so its exact role should be verified against the machine-specific parts list.
8. What symptoms can indicate MPCV wear?
Possible symptoms include unstable separator pressure, abnormal loading or unloading behavior, excessive pressure drop, or irregular compressor operating conditions. Diagnosis should precede component replacement.
9. Can 47690462001 be used on any Ingersoll Rand compressor?
No. Its documented application is configuration-specific, particularly RS45–75I/N machines. Compressor model, serial number, valve configuration, and applicable parts list should be verified before installation.
10. What should be checked after rebuilding the MPCV?
Technicians should verify correct component installation, sealing integrity, valve movement, operating pressure, loading/unloading response, and overall compressor performance before returning the machine to service.
