Introduction
The Ingersoll Rand 47552954001 / 39404157 Temperature Control Valve Maintenance Kit listing combines a temperature-control maintenance reference with a specific sealing component used on compatible compressor assemblies.
47552954001 is cataloged as a temperature-control valve maintenance kit for R90–160, IR90–160, and IE R90–160 compressor configurations. It belongs to a larger R90–160 service-parts family that includes intake-valve, gearbox, hose, and preventive-maintenance kits.
The independently documented 39404157 is an O-ring for a 7/16-20 SAE straight-thread fitting. Ingersoll Rand parts information specifies an approximate inside diameter of 0.351 inch, cross-sectional width of 0.072 inch, and tube size of 1/4 inch.
The O-ring is a sealing component rather than a regulating element. Its role is to maintain a fluid-tight interface between compatible SAE fittings and the mating component. Although physically small, the seal is important because leakage around a temperature-control or lubricant-circuit connection can affect equipment cleanliness, maintenance reliability, and potentially oil-system performance.
39404157 is also documented as a Viton O-ring. Material identification matters because elastomer compatibility depends on the fluid, temperature, pressure, and service environment. An O-ring that appears dimensionally similar may not provide equivalent performance if its material or hardness is unsuitable.
The documented fitting specification is 7/16-20 SAE straight thread. This is important when selecting a replacement because SAE straight-thread connections rely on the appropriate sealing arrangement rather than simply matching the nominal thread diameter.
In compressor maintenance, O-rings should generally be inspected whenever a sealed fitting or valve connection is disassembled. A seal that has been compressed for an extended period may not reseat correctly after removal, even if there is no obvious visual damage.
Installation technique is also important. The sealing surface should be clean and free of burrs, scratches, or contamination. The O-ring should be correctly seated without twisting, cutting, or excessive stretching during assembly.
The 47552954001 temperature-control valve maintenance kit should not be confused with an intake-valve service kit. For example, 47553880001 is separately cataloged as an intake-valve service kit for the same general R90–160 family. These two maintenance references address different compressor systems.
Other Ingersoll Rand documentation also lists 39404157 in airend and compressor assemblies. One parts reference shows it as an O-ring with an approximate 0.351-inch ID and 0.072-inch width, confirming its use as a defined sealing component rather than a generic maintenance seal.
The exact internal contents of 47552954001 were not independently verified from the available public documentation. Therefore, 39404157 should be described as an associated individual sealing reference rather than being represented as a confirmed complete kit component.
The available documentation also does not reliably establish the complete packaged dimensions or weight of 47552954001. The O-ring itself is a small component, but a reliable packaged weight was not established and should not be fabricated.
The supplied pair is treated as one product listing as requested. Public records independently establish 47552954001 as the R90–160 temperature-control valve maintenance kit and 39404157 as the 7/16-20 SAE straight-thread Viton O-ring.
