Introduction
The Ingersoll Rand 47704537001 / 47622840001 Bearing Oil Injection Hose is a specialized compressor component designed for bearing-oil service.
The available product documentation identifies 47622840001 as “Hose, Bearing Oil Injection, PTFE 5/8ID Dash 12 X Dash 10.” This description establishes the principal technical characteristics: bearing-oil injection service, PTFE hose construction, 5/8-inch internal diameter, and a Dash 12 × Dash 10 end configuration.
Bearing lubrication is a critical function in compressor operation. The hose provides the flexible connection required to route oil toward the applicable bearing circuit while accommodating the mechanical arrangement of the compressor package.
The PTFE construction is an especially important identification feature. Replacement should therefore be based on the complete component specification rather than simply selecting a conventional rubber hydraulic hose with a similar internal diameter.
The 5/8-inch ID establishes the principal flow passage, while the Dash 12 × Dash 10 designation provides additional information about the hose-end configuration. These details should be checked against the removed component and the equipment-specific parts documentation before installation.
Related Ingersoll Rand parts listings show other bearing-oil injection hoses with the same general PTFE 5/8-inch / Dash 12 × Dash 10 description, including 47524521001 and 47581507001. Their existence demonstrates that similar-looking hose references can occur across different equipment configurations, so part-number verification remains essential.
Ingersoll Rand's own parts guidance recommends selecting the equipment model through its Parts Finder to identify genuine OEM components designed for the specific compressor. Its technical-documentation archive further notes that the serial number is the key identifier for the actual equipment configuration.
During maintenance, the hose should be inspected for abrasion, cracking, deformation, leakage, contamination, and stress at the fittings. Any evidence of restricted oil flow or damage to the connection points should be investigated before the compressor is returned to service.
Available supplier information gives a weight field of 5.050000, but the unit is not clearly identified, so it should not be presented as a confirmed product weight.
The two supplied references are treated as one product listing as requested. Public documentation directly verifies 47622840001, while the relationship between 47704537001 and 47622840001 is not independently established in the available records. Final compatibility should therefore be confirmed against the compressor model, serial number, and applicable OEM parts documentation.
